    Abstract: 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 [A] and a polyisocyanate compound[B] satisfying at least one of the following conditions (i) and (ii): (i) the polyol compound [A] is a high-molecular weight polyol compound, and (ii) the polyisocyanate compound is a polyoxyalkylene segment-containing polyisocyanate compound. 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.
