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 T<T<Twhere the glass transition temperature of the charge transport layer is represented by T(°C.), the temperature of the mold by T(°C.), and the temperature of the support by T(°C.).
