PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that has suppressed an increase in residual potential.SOLUTION: An electrophotographic photoreceptor includes a conductive support 2, an undercoat layer 4, and a photosensitive layer 3. The undercoat layer 4 is provided on the conductive support 2, formed of a cured film of a composition containing a binder resin, metal oxide particles, an electron-accepting compound having an anthraquinone structure and is contained in the amount of 1 part by weight or more and 5 parts by weight or less relative to 100 parts by weight of the metal oxide particles, and an isocyanate compound, and has the amount of weight change in a temperature range from 0°C to 230°C of 0.05 weight% or more and 0.8 weight% or less in differential heat/thermogravimetry simultaneous measurement (TG/DTA measurement). |
