Abstract
An electrophotographic photoreceptor including an electroconductive substrate and a photosensitive layer located overlying the electroconductive substrate, wherein the photosensitive layer comprises units obtained from a radical polymerizing monomer, in which an aliphatic group having two radical polymerizing groups and a charge transporting group including no radical polymerizing group are connected to each other in a single bond, at the surface thereof.
Claims16
An electrophotographic photoreceptor, comprising:
- an electroconductive substrate;
- and
- a photosensitive layer located overlying the electroconductive substrate,
- wherein the photosensitive layer comprises units obtained from a radical polymerizing monomer at a surface thereof, wherein the radical polymerizing monomer comprises
- (i) an aliphatic group portion of formula (1)
- wherein Ra and Rb each, independently, represent a hydrogen atom or a methyl group, and
- (ii) a hole transporting group portion including no radical polymerizing group selected from the group consisting of a vinyl group, an allyl group, an acryloyloxy group, a methacaryloyloxy group and an acrylamide group,
- wherein the aliphatic group portion (i) and the hole transporting group portion (ii) are connected to each other by a single bond.
