Abstract:
The present invention provides an electrophotographic photosensitive member in which a photosensitive layer has strong close adhesiveness even when used repeatedly, and a positive ghost is reduced. An undercoat layer of the electrophotographic photosensitive member contains a cured product of an electron transport material having a polymerizable functional group; a polyolefin resin having at least one group/structure selected from the group consisting of a carboxyl group, an alkoxycarbonyl group and an anhydrous carboxylic acid structure, and a substituted or unsubstituted phenyl group; and an isocyanate compound having two or more isocyanate groups.

Claim (Index 4):
The electrophotographic photosensitive member according to  claim 1 , wherein the electron transport material included in the undercoat layer is a compound represented by Chemical Formula (A1) below. (In Formula (A1), R 15  and R 16  are each independently a substituted or unsubstituted alkyl group having 2 to 6 carbon atoms, a group derived by substituting at least one CH 2  in a main chain of a substituted or unsubstituted alkyl group having 3 to 6 carbon atoms in the main chain with an oxygen atom, a group derived by substituting at least one CH 2  in the main chain of the substituted or unsubstituted alkyl group having 3 to 6 carbon atoms in the main chain with NR 124 , a group derived by substituting at least one C 2 H 4  in the main chain of the substituted or unsubstituted alkyl group having 3 to 6 carbon atoms in the main chain with COO, or a substituted aryl group, R 124  represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and a substituent of the substituted alkyl group, a group derived by substituting at least one CH 2  in the main chain of the substituted alkyl group with an oxygen atom, a group derived by substituting at least one CH 2  in the main chain of the substituted alkyl group with NR 124 , and a group derived by substituting at least one C 2 H 4  in the main chain of the substituted alkyl group with COO is a group selected from the group consisting of an alkyl group having 1 to 5 carbon atoms, a benzyl group, an alkoxycarbonyl group, a phenyl group, a hydroxyl group, a thiol group, an amino group, and a carboxyl group, and the substituent of the substituted aryl group is a group selected from the group consisting of a halogen atom, a cyano group, a nitro group, a methyl group, an ethyl group, an isopropyl group, an n-propyl group, an n-butyl group, an acyl group, an alkoxy group, an alkoxycarbonyl group, a hydroxyl group, a thiol group, an amino group, and a carboxyl group, and comprises at least one hydroxyl group or carboxyl group. R 11  to R 14  each independently represent a hydrogen atom, a halogen atom, a cyano group, a nitro group, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, or a substituted or unsubstituted aryl group).
