Abstract

A cartridge used for forming an image on a recording material include a memory for storing information; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of the memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of the memory inserted in the supporting portion. With respect to a direction crossing a longitudinal direction of the cartridge and crossing a thickness direction of the memory, a width of the preventing portion is smaller than a width of the memory inserted in the slit.

First claim

What is claimed is:

1 . A cartridge used for forming an image on a recording material, comprising:
a memory for storing information; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of said memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of said memory inserted in said supporting portion, wherein with respect to a direction crossing a longitudinal direction of said cartridge and crossing a thickness direction of said memory, a width of said preventing portion is smaller than a width of said memory inserted in the slit.

2 . A cartridge according to claim 1 , wherein with respect to the longitudinal direction of said cartridge, a depth length of said preventing portion is longer than a depth length of said memory inserted in the slit.

3 . A cartridge according to claim 1 , wherein said preventing portion is provided, on said second cartridge constituent member, as a projected portion projected in an inserting direction of said memory.

4 . A cartridge according to claim 1 , wherein between said memory and said preventing portion, a gap is provided.

5 . A cartridge according to claim 1 , wherein with respect to the direction crossing the longitudinal direction of said cartridge and the thickness direction of said memory, the width of said memory is larger than 3 times the width of said preventing portion and is smaller than 6 times the width of said preventing portion.

6 . A cartridge according to claim 1 , further comprising a developer carrying member for supplying the developer to an image bearing member on which a latent image is to be formed, and a developer accommodating portion in which the developer is accommodated.

7 . A cartridge according to claim 1 , further comprising a rotatable image bearing member on which a latent image is to be formed.

8 . A cartridge according to claim 1 , wherein said preventing portion has flexibility.

9 . A cartridge according to claim 1 , wherein said first cartridge constituent member is a side wall member, and said second cartridge constituent member is a container for accommodating a developer.

10 . An image forming apparatus comprising:
a cartridge according to claim 1 ; mounting means for detachably mounting said cartridge; feeding means for feeding a recording material; and a main assembly electrical contact for being electrically connected with the memory.

11 . A manufacturing method of a cartridge used for forming an image on a recording material including,
a memory for storing information; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of said memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of said memory inserted in said supporting portion, wherein with respect to a direction crossing a longitudinal direction of said cartridge and crossing a thickness direction of said memory, a width of said preventing portion is smaller than a width of said memory inserted in the slit, said manufacturing method comprising: inserting the memory into the slit; and assembling the first and second cartridge constituent member with each other.

12 . A manufacturing method according to claim 11 , wherein the preventing portion has flexibility.
