    摘要: An electrophotographic photosensitive member is constituted by an electroconductive support, and an intermediate layer and a photosensitive layer disposed in this order on the support. The intermediate layer comprises a reaction product of a mixture including a polyol compound [I], a polyol compound [II] having an OH equivalent different from that of the polyol compound [I] and a polyisocyanate compound. The polyol compound [I] is a polyether polyol compound having an OH equivalent of at least 500 and 2-60 OH groups per molecule; and the polyol compound [II] is a polyol compound having an OH equivalent of at most 300. The photosensitive member shows stable electrophotographic performances over wide environmental conditions from low temperature--low humidity to high temperature high humidity due to the intermediate layer.
