Abstract:
1. An organic photoreceptor unit comprising: a conductive base unit; a charge generating layer formed on said conductive base unit; a first charge transport layer that is formed on said charge generating layer and contains a first bonding resin and a first charge transport material; and a second charge transport layer that is formed on said first charge transport layer and contains a second bonding resin including polycarbonate resin having recurring units represented by general formulas I, II, III or IV, fluorine resin particles and a second charge transport material, wherein the content of the second charge transport material relative to said second bonding resin is larger than the content of the first charge transport material relative to said first bonding resin; and wherein said first charge transport layer and said second charge transport layer each contain an antioxidant, and the content of the antioxidant relative to said second bonding resin is larger than the content of the antioxidant relative to said first bonding resin and within the range of 0.5 to 30 parts by weight per 100 parts by weight of the second bonding resin: wherein, R wherein R wherein, R wherein, R
