Abstract
In an electrophotographic photosensitive member having a charge generation layer and a charge transport layer formed by a dip-coating method, a length (H) expressed by the formula ##EQU1## of the charge generation layer is substantially the same as that of a film thickness changing portion of the charge transport layer (where V(t) represents an accelerating velocity from a velocity V1 to a velocity V2, and a substrate is pulled up at the velocity V1 until a time T1 has elapsed (t=T1) after the pulling up operation was started (t=0), is pulled up upon increasing the velocity from V1 to V2 until a time T2 has elapsed (t=T2) after the time T1, and thereafter is pulled up at the velocity V2 until a coating operation is completed after the time T2).
