Document Type and Number:
Japanese Patent JP6850201
Kind Code:
B2
Abstract:
To provide an electrophotographic photoreceptor improved both in loss of density of the output image at an initial stage of repeated use and transferability of the toner after repeated use.SOLUTION: A electrophotographic photoreceptor has a surface layer containing a polysiloxane modified polyacrylate, an alkyl fluoride group-containing polyacrylate, and polytetrafluoroethylene particles, in which a ratio (R/R) of a ratio (R) of a fluorine atom derived from the alkyl fluoride group-containing polyacrylate and polytetrafluoroethylene particles to the total number of atoms except for a hydrogen atom in the outer most surface of the surface layer and a ratio (R) of the silicon atom derived from the polysiloxane modified polyacrylate to the total number of atoms except for the hydrogen atom is not less than 0 and not more than 7, and the ratio (R/R) at the position of a depth 0.1 μm from the outermost surface of the surface layer is not less than 0 and not more than 0.5.SELECTED DRAWING: None
