Abstract

A packing member for packing a cartridge detachably mountable to an image forming apparatus is molded with a thin resin material plate and includes: (i) a frame portion including an opening as an entrance for the cartridge, a first recessed portion for accommodating the cartridge, and a first limiting portion for limiting a position of the cartridge with respect to a direction perpendicular to a longitudinal direction of the cartridge; and (ii) a cap portion for openably covering the opening. The cap portion includes a second limiting portion for limiting movement of the cartridge, positionally-limited by the first limiting portion, in a direction in which the cartridge is spaced from the first limiting portion.

First claim

1 - 36 . (canceled)

37 . A packing member for packing a cartridge that includes a photosensitive drum on which an electrostatic latent image is to be formed and is detachably mountable to an image forming apparatus, wherein said packing member is molded with a thin resin material plate, said packing member comprising:
(i) a first portion including (a) an opening as an entrance for the cartridge, (b) a recessed portion for accommodating the cartridge, and (c) a first limiting portion and a second limiting portion for limiting a position of the cartridge; and (ii) a second portion for openably covering the opening, wherein said first limiting portion and said second limiting portion are provided apart from each other with respect to a direction perpendicular to a longitudinal direction of the cartridge, and said first limiting portion and said second limiting portion contact portions of the cartridge excluding a region of the photosensitive drum where the electrostatic latent image is to be formed.

38 . A packing member according to claim 37 , wherein said packing member is formed by subjecting the thin resin material plate to vacuum air pressure molding.

39 . A packing member according to claim 37 , wherein said second portion includes a second opening as an entrance for the cartridge and a recessed portion for forming a space for accommodating the cartridge together with said recessed portion of said first portion when the opening is covered.

40 . A packing member according to claim 37 , wherein said second portion is integrally molded with said first portion so as to be movable to a closed position in which the opening is covered and to an open position in which the opening is open.

41 . A packing member according to claim 37 , wherein said first limiting portion and said second limiting portion are configured to positionally limit the cartridge so as to prevent a surface of the photosensitive drum from contacting an inner surface of said recessed portion.

42 . A packing member according to claim 37 , wherein said first portion includes a flange portion, provided outside the opening, for connecting to said second portion in a state in which said second portion is located at a closed position.

43 . A packing member according to claim 37 , wherein said first portion includes a center portion between said first limiting portion and said second limiting portion, and said center portion is provided so as to form a gap between an inner surface of said recessed portion and said cartridge.

44 . A cartridge including a photosensitive drum on which an electrostatic latent image is to be formed, packed in a packing member, and detachably mountable to an image forming apparatus, wherein said packing member is molded with a thin resin material plate and said packing member comprises:
(i) a first portion including (a) an opening as an entrance for said cartridge, (b) a recessed portion for accommodating said cartridge, and (c) a first limiting portion and a second limiting portion for limiting a position of said cartridge; and (ii) a second portion for openably covering the opening, wherein said first limiting portion and said second limiting portion are provided apart from each other with respect to a direction perpendicular to a longitudinal direction of the cartridge, and said first limiting portion and said second limiting portion contact portions of said cartridge excluding a region of the photosensitive drum where the electrostatic latent image is to be formed.

45 . A cartridge according to claim 44 , wherein said packing member is formed by subjecting said thin resin material plate to vacuum air pressure molding.

46 . A cartridge according to claim 45 , wherein said second portion includes a recessed portion for forming a space for accommodating said cartridge together with said recessed portion of said first portion when the opening is covered.

47 . A cartridge according to claim 44 , wherein said second portion is integrally molded with said first portion so as to be movable to a closed position in which the opening is covered and to an open position in which the opening is open.

48 . A cartridge according to claim 44 , wherein said first limiting portion and said second limiting portion are configured to positionally limit said cartridge so as to prevent a surface of said photosensitive drum from contacting an inner surface of said recessed portion.

49 . A cartridge according to claim 44 , wherein said first portion includes a flange portion, provided outside the opening, for connecting to said second portion in a state in which said second portion is located at a closed position.

50 . A cartridge according to claim 44 , wherein said first portion includes a center portion between said first limiting portion and said second limiting portion, and said center portion is provided so as to form a gap between an inner surface of said recessed portion and said cartridge.
