Conductive member for electrophotographic machine
To provide a conductive member for an electrophotographic machine that is capable of preventing hardening degradation of a surface layer that is caused by an ionic conductive agent contained in a conductive rubber elastic body layer, allowing the surface layer to be improved in durability. A conductive member 10 for an electrophotographic machine includes a conductive rubber elastic body layer 14 containing crosslinked rubber and an ionic conductive agent, and a surface layer 16 provided on an outer periphery of the conductive rubber elastic body layer 14, wherein the surface layer 16 contains a polymer and polyphenol. Examples of the polyphenol include a tannin, gallic acid, ellagic acid, pyrogallol, catechin, and chlorogenic acid.
End member, photoreceptor drum unit, developing roller unit, and process cartridge
An end member (30) comprises: a tubular bearing member (40); and a shaft member (50), wherein the shaft member comprises: a shaft-like rotating shaft (51) which is disposed coaxially to the bearing member, and moves in the shaft line direction by rotating around a shaft line with respect to the bearing member; and a tip end member (55) which is disposed coaxially to the rotating shaft, and where a rotating force receiving member (58) provided with an engaging member (60) which engages with a driving shaft (70) of the image forming apparatus main body is disposed at a tip end, wherein a rotating force around the shaft line is transmitted to the rotating force receiving member, the rotating shaft, and the bearing member, in this order, and the rotating force receiving member moves to be inclined with respect to the shaft line.
