ABSTRACT:
The present invention relates to an organic photoreceptor unit that has a conductive base unit, a charge generating layer formed on the conductive base unit, a first charge transport layer that is formed on the 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 the first charge transport layer and contains a second bonding resin including denatured polycarbonate resin, fluorine resin particles and a second charge transport material, wherein the content of the second charge transport material relative to the second bonding resin is larger than the content of the first charge transport material relative to the first bonding resin.
