ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor having an anodic oxide film which is not cracked. SOLUTION: This electrophotographic photoreceptor is constituted by forming the anodic oxide film on a supporting body for the electrophotographic photoreceptor and forming a photoreceptive layer on the anodic oxide film, and pore sealing processing is performed to the anodic oxide film. The sealing degree of the anodic oxide film obtained just after the sealing processing is compared with the sealing degree thereof obtained one month after the sealing processing is performed. Such photoreceptors that the difference of the sealing degree is≤50% of the sealing degree thereof just after the sealing processing are accepted. COPYRIGHT: (C)2003,JPO
