Abstract
An electrophotographic photoreceptor is disclosed. The photoreceptor has a resin layer comprising a siloxane resin formed by hardening a compound represented by Formula 1, 2 or 3, or a hydrolyzed product which has a structural unit having a charge transportation ability, and a ratio M1/M2 of the sum of the amount in moles M1 of the compound represented by Formula 1 and that represented by Formula 2 to the amount in moles of the compound represented by Formula 3 is within the range of from 0.01 to 1.Si(OR1′)4  Formula 1 R1Si(OR2′)3  Formula 2 R1R2Si(OR3′)2  Formula 3 wherein the formulas, R1 and R2 each represented an alkyl group having one to ten carbon atoms, a phenyl group, an aryl group, a vinyl group, an amino group, &ggr;-clycidoxypropyl group, a &ggr;-methacryloxypropyl group, or a CnF2n+1C2H4— group; R1′, R2′ and R3′ each represented an alkyl group and the groups represented by R1′, R2′ and R3′ may be the same or different from each other.An image forming method, image forming apparatus, and process cartridge employing the photoreceptor are also disclosed.
