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

An electrophotographic image forming method in which after transferring a toner image on an electrophotographic photoreceptor onto a recording material, the residual toner on said photoreceptor is removed employing an elastic body rubber blade, wherein said photoreceptor has structural units exhibiting charge transport performance;

• also has a resin layer comprising a siloxane based resin having a crosslinked structure;
• rubber of the rubber blade has an impact resilience at 25±0.2° C. between 20 and 75;
• said rubber blade is brought into contact with said photoreceptor in a counter position to a direction of rotation of said photoreceptor so that the residual toner on said photoreceptor thereby is removed.

The electrophotographic image forming method of claim or 2 wherein the resin layer comprises fine organic particles having an average particle diameter of 0.05 to 10 μm.

An electrophotographic image forming apparatus in which, after transferring a toner image on an electrophotographic photoreceptor onto a recording material, the residual toner on said photoreceptor is removed employing an elastic body rubber blade, wherein said photoreceptor has a resin layer comprising a siloxane based resin having a crosslinked structure and structural units exhibiting charge transport performance;

• said rubber blade is brought into contact with said photoreceptor in a counter position to a direction of rotation of said photoreceptor;
• and the residual toner on said photoreceptor is removed by said rubber blade vibrating at an amplitude of 10 to 200 μm.

An electrophotographic image forming apparatus in which, after transferring a toner image on an electrophotographic photoreceptor onto a recording material, the residual toner on said photoreceptor is removed employing an elastic body rubber blade, wherein said photoreceptor has structural units exhibiting charge transport performance;
