PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that suppresses the occurrence of ghost, while being highly sensitive to positive charge.SOLUTION: An electrophotographic photoreceptor 10 includes: a conductive substrate 4; and a photosensitive layer 2 of a single layer-type that is provided on the conductive substrate 4, is configured by including a binder resin, a charge generating material, a hole transporting material, and an electron transporting material and has the half exposure amount when positively charged of 0.18 μJ/cmor less, and the half exposure amount when negatively charged of twice or more and 12 times or less the half exposure amount when positively charged. |
