(57) [Problem] To provide an organic electrophotographic photosensitive member excellent in electric characteristics and capable of obtaining a good image. SOLUTION: In an organic electrophotographic photoreceptor having at least an undercoat layer and a photosensitive layer on a conductive substrate, the undercoat layer has at least an average primary particle diameter of 100 nm or less and titanium oxide particles having the following general formula (I) An organic electrophotographic photoreceptor comprising a copolymerized polyamide having a diamine component represented by the formula (1) as a constituent component. Embedded image Each independently represents a cyclohexyl ring which may have a substituent, and R 1 and R 2 each independently represent hydrogen, an alkyl group, an alkoxy group, or an aryl group. ) |
