ELECTROPHOTOGRAPHIC PHOTORECEPTOR, IMAGE FORMING METHOD, TONER AND PROCESS CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor whose mechanical characteristics such as printing durability, wear resistance, flaw resistance and sliding property are excellent and whose other characteristics such as coating property are not spoiled in repetitive use, and an image forming method using the electrophotographic photoreceptor and hardly causing filming, welding and flaw, and toner and a process cartridge. SOLUTION: This electrophotographic photoreceptor having an organic layer on a conductive supporting body satisfies following conditions 60 deg.C<=T1p<=100 deg.C, 60 deg.C<=T2p<=100 deg.C and|T1a-T1b|-|T2a-T2b|>5 deg.C when it is assumed that a heat absorption peak, a heat absorption starting point and a heat absorption finishing point in a 1st temperature rise stage are T1p, T1a and T1b, respectively, and a heat absorption peak, a heat absorption starting point and a heat absorption finishing point in a 2nd temperature rise stage are T2p, T2a and T2b, respectively, on an endothermic curve by the differential scanning calorimeter(DSC) of the organic layer. Thus, the electrophotographic photoreceptor, the image forming method using the electrophotographic photoreceptor, the toner and the process cartridge are provided.
