<P>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that suppresses the occurrence of black dots in a non-image part after successive image formation. <P>SOLUTION: An electrophotographic photoreceptor includes: a conductive substrate 1; an undercoat layer 2 that is provided on the conductive substrate, and contains metal oxide particles, a reactive acceptor material, and a binder resin; and a photosensitive layer 3 that is provided on the undercoat layer. The amount of the reactive acceptor material extracted when the reactive acceptor material is dissolved in 10 ml of an organic solvent for dissolving the reactive acceptor material per 100 mg of the undercoat layer is within a range of 1×10<SP POS="POST">-5</SP>mol/L or more and 1×10<SP POS="POST">-4</SP>mol/L or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
