Abstract:
An electrophotographic photosensitive member comprising an aluminum support, a subbing layer containing a polyamide resin, a charge generation layer and a charge transport layer provided on said aluminum support in this order, whereinsaid charge transport layer contains a polycarbonate resin as a binder resin, said subbing layer is present on said aluminum support without any intervening layer therebetween and has a thickness from 0.3 &mgr;m to 1 &mgr;m, said charge generation layer contains a charge-generating material in an amount of more than 2 parts by weight and not more than 5 parts by weight based on 1 part by weight of a binder resin, wherein said charge-generating material is an azo pigment, and said aluminum support has a surface roughness in which a maximum height RmaxD, a 10-point average roughness Rz, an arithmetic-mean roughness Ra and an unevenness average distance Sm fulfill the following conditions: 1.2 &mgr;m&lE;RmaxD&lE;5.0 &mgr;m, 1.2 &mgr;m&lE;Rz&lE;3.0 &mgr;m, 0.15 &mgr;m&lE;Ra&lE;0.5 &mgr;m, 30 &mgr;m<Sm&lE;80 &mgr;m.
