Abstract

Official abstract text for this publication.

A process cartridge including a photosensitive drum; a developing roller; a rotatable roller having a rotation shaft in a position deviated from an axis of the developing roller; an Oldham coupling member at an end portion of the shaft of the rotatable roller; an urging member for urging the drive receiving portion; a supporting portion supporting the drive receiving portion; an abutting portion receiving the supporting portion urged by the urging member, an elastic sheet positioned to contact at least part of the Oldham coupling member, wherein the abutting portion is positioned outside an outer periphery of the drum on a plane perpendicular to the shaft of the rotatable roller.

First claim

Opening claim text (preview).

1 . A process cartridge comprising: a photosensitive drum; a rotatable developing roller for developing an electrostatic latent image formed on said photosensitive drum; a rotatable roller having a rotation shaft in a position deviated from an axis of said developing roller, for transmitting a driving force to said developing roller; an Oldham coupling member disposed at an end portion of the shaft of said rotatable roller, for receiving a driving force to be transmitted to said developing roller; an urging member for urging said drive receiving portion in the direction crossing the shaft of said rotatable roller; a supporting portion for rotatably supporting said drive receiving portion so as to be movable together with said drive receiving portion toward said rotatable roller in the direction crossing the shaft of said rotatable roller; and an abutting portion for receiving said supporting portion urged by said urging member, an elastic sheet positioned to contact at least part of the Oldham coupling member, wherein said abutting portion is positioned outside an outer periphery of said photosensitive drum on a plane perpendicular to the shaft of said rotatable roller. 2 . (canceled)
