| description | PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which effectively prevents occurrence of black spots even when image formation is performed under any use condition, and an image forming apparatus equipped with the electrophotographic photoreceptor. SOLUTION: The electrophotographic photoreceptor has a photosensitive layer containing a binder resin, a hole transport agent and a charge generating agent, and the image forming apparatus uses the same. An amine compound represented by general formula (1) is contained as the hole transport agent, and the contact angle of deionized water to the photosensitive layer (measurement temperature: 25°C) is set to a value of ≥100°. In the formula (1), Ra-Rg are each independent and a 1-20C alkyl group or the like; and X1and X2are each independent and a substituent such as butadienylbenzene. COPYRIGHT: (C)2008,JPO&INPIT |
