    • PURPOSE: Provided is an electrophotographic photosensitive member having a cured surface layer which has excellent wear resistance and a high hardness without adding any curing catalyst, and does not cause any deterioration of the original charge transport performance. CONSTITUTION: The electrophotographic photosensitive member includes a support(4) and a photosensitive layer disposed thereon. The electrophotographic photosensitive member has a surface layer(1) which contains at least one charge-transporting material(2) and conductive particles; and a polymer obtained by polymerizing at least one selected from the group consisting of a polyhydroxymethyl bisphenol monomer having 2 or 3 benzene rings and 2 to 4 hydroxymethyl groups; a polyhydroxymethyl bisphenol oligomer having a structure in which a bisphenol monomer having 2 or 3 benzene rings is condensed, and having 2 to 4 hydroxymethyl groups; a polyhydroxymethyl trisphenol monomer having 3 or 4 benzene rings and 2 to 6 hydroxymethyl groups; and a polyhydroxymethyl trisphenol oligomer having a structure in which a trisphenol monomer having 3 or 4 benzene rings is condensed, and having 2 to 6 hydroxymethyl groups.
    • 目的:提供具有固化表面层的电子照相感光构件,其具有优异的耐磨性和高硬度,而不添加任何固化催化剂,并且不会导致原始电荷输送性能的任何劣化。 构成:电子照相感光构件包括支撑体(4)和设置在其上的感光层。 电子照相感光构件具有包含至少一种电荷输送材料(2)和导电颗粒的表面层(1) 以及通过聚合选自具有2或3个苯环的多羟基甲基双酚单体和2至4个羟甲基的至少一种而获得的聚合物; 具有其中具有2或3个苯环的双酚单体缩合并具有2至4个羟甲基的结构的多羟基甲基双酚低聚物; 具有3或4个苯环和2至6个羟甲基的多羟甲基三酚单体; 和具有3或4个苯环的三酚单体缩合并具有2〜6个羟甲基的结构的多羟甲基三酚低聚物。
