PROCESS FOR PRODUCING ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER
First Claim
1. A process for producing an electrophotographic photosensitive member;
- the process comprising the step of bringing i) the surface of an electrophotographic photosensitive member comprising at least a cylindrical support and a charge transport layer provided thereon and ii) a mold having a fine unevenness surface profile, into pressure contact with each other to transfer the fine unevenness surface profile to the surface of the electrophotographic photosensitive member, wherein;
the mold and the cylindrical support are so temperature-controlled as to be T3<
T1<
T2 where the glass transition temperature of the charge transport layer is represented by T1 (°
C.), the temperature of the mold by T2 (°
C.), and the temperature of the cylindrical support by T3 (°
C.).

Abstract
A process for producing an electrophotographic photosensitive member, which has the step of bringing i) the surface of an electrophotographic photosensitive member having at least a charge transport layer on a cylindrical support and ii) a mold having a fine unevenness surface profile into pressure contact with each other to transfer the fine unevenness surface profile to the surface of the electrophotographic photosensitive member. The mold and the support are so temperature-controlled as to be T3<T1<T2 where the glass transition temperature of the charge transport layer is represented by T1 (° C.), the temperature of the mold by T2 (° C.), and the temperature of the support by T3 (° C.).
