Abstract
Official abstract text for this publication.
A process cartridge includes a photosensitive drum; a developing roller; a developer supplying roller, provided in contact with the developing roller; a driving force receiving portion provided at a shaft end of the supplying roller; a first driving force transmitting portion; a second driving force transmitting portion; flexible sheets provided adjacent to an engaging portion between the first portion and the second portion to intermittently contact the second portion with rotation of the second portion, wherein a rotational direction of the roller is opposite to that of the roller, and a peripheral speed of the roller is larger than that of the roller.
First claim
Opening claim text (preview).
1 . A process cartridge comprising: (i) a photosensitive drum; (ii) a rotatable developing roller for developing an electrostatic latent image formed on said photosensitive drum; (iii) a developer supplying roller, provided in contact with said developing roller, for supplying a developer to said developing roller; (iv) a driving force receiving portion for receiving a driving force, wherein said driving force receiving portion is provided at a shaft end portion of said developer supplying roller and is movable in a direction crossing a shaft of said developer supplying roller; (v) a first driving force transmitting portion configured to transmit the driving force received by said driving force receiving portion, to said developing roller, wherein said first driving force transmitting portion is provided on said developer supplying roller; and (vi) a second driving force transmitting portion provided on said developing roller and configured to transmit the driving force by engaging with said driving force transmitting portion, (v) flexible sheets provided adjacent to an engaging portion between said first driving force transmitting portion and second driving force transmitting portion and configured to intermittently contact said second driving force transmitting portion with rotation of said second driving force transmitting portion, wherein a peripheral movement direction of said developing roller is opposite to a peripheral movement direction of said developer supplying roller, and a peripheral speed of said developer supplying roller is larger than a peripheral speed of said developing roller. 2 .
