Electrophotographic photoreceptor, electrophotographic image forming method, electrophotographic image forming apparatus and processing cartridge

An electrophotographic image forming method including electrostatic charging on a photoreceptor, imagewise exposing on the photoreceptor to form a latent image, developing the latent image by a developer and cleaning residual toner on the photoreceptor, wherein the electrophotographic photoreceptor has on a support, 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, wherein 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, a γ-clycidoxypropyl group, a γ-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.
