Title:
END MEMBER, PHOTOSENSITIVE DRUM UNIT, AND PROCESS CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2016/204246
Kind Code:
A1
Abstract:
The present invention is an end member (30) to be placed at an end of a columnar rotatable body attached to an image forming device body (2). The end member comprises: a tubular bearing member (40); and a shaft member (50) held by the bearing member (40). The shaft member (50) has a rotary shaft (51) which is rotatable around the axis and which is movable in the axis direction, and a rotary force receiving member (55) which is placed at one end of the rotary shaft (51) and which includes an engagement member (58) to engage with a driving shaft (70) of the image forming device body (2). The engagement member (58) is switchable between a posture engaging with the driving shaft (70) and a posture not engaging with the driving shaft (70). The maximum static friction coefficient in movement, in the rotational axis direction, of the rotary shaft (51) with respect to the bearing member (40) is 0.40 or less when a force applied in a direction perpendicular to the friction force direction is 2.5-10.5 N.
