Electrophotographic photosensitive member and apparatus using same

摘要

A photosensitive member suitable for use in an electrophotographic apparatus 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 polyol compound comprising at least one of a polyol compound (I) represented by Formula (1) shown below and a phosphated polyol compound with a polyisocyanate compound: (* CHEMICAL STRUCTURE *) Formula (1) wherein A denotes (* CHEMICAL STRUCTURE *) B denotes -R4-O-, A and B may be connected at random or in blocks with each other, Z denotes an active hydrogen compound residue; R1 is an alkylene group having 1-9 carbon atoms; R2 is an alkylene group having 1-10 carbon atoms; R3 is an alkyl group, alkenyl group, aryl group or aralkyl group having 1-20 carbon atoms; R4 is an alkylene group having 2-10 carbon atoms; k is a number of 1-12 m is a number of 1-250; n is a number of 0-100; and p is a number of 0-5.
