ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS FOR PRODUCING THE ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND ELECTROPHOTOGRAPHIC DEVICE

摘要

Disclosed is an electrophotographic photoreceptor which is equipped with an undercoating layer capable of attaining stable potential characteristics in all environments ranging from low temperature and low humidity environments to high temperature and high humidity environments, suppressing the occurrence of printing defects and simultaneously attaining the recovery from transfer and the recovery from high light fatigue even in a wide variety of usage and operating environments, and as a result, which can print good images having little or no image defect and density difference by virtue of the provision of.  Also disclosed are a process for producing the electrophotographic photoreceptor and an electrophotographic device with the electrophotographic photoreceptor mounted thereon. An electrophotographic photoreceptor (7) comprises an undercoating layer (2) and a photosensitive layer (3) stacked in serial order on an electroconductive base (1).  The undercoating layer (2) comprises metal oxide fine particles having a surface treated with an organic compound, and a copolymer resin synthesized using a dicarboxylic acid, a diol, a triol, and a diamine as indispensable constituent monomers.
