Electrophotographic photoconductor, electrophotographic process, electrophotographic apparatus, and process cartridge

An electrophotographic process, comprising:

• charging an electrophotographic photoconductor,
• exposing the charged electrophotographic photoconductor to a recording light to form an electrostatic latent image,
• developing the electrostatic latent image by means of a developing agent to form a toner image, and
• transferring the toner image onto a transfer material,
• wherein the electrophotographic photoconductor comprises
• a photoconductive layer,
• a protective layer, and a
• conductive support,
• wherein the protective layer is disposed as the outermost layer of the photoconductive layer, and 20% by volume to 60% by volume of fine particles of fluorine-contained resin and at least one compound selected from the group consisting of amine aromatic compounds and hydroxy aromatic compounds are incorporated into the protective layer;
• wherein said fine particles of fluorine-contained resin having 0.3 to 0.4 μm of secondary particle diameter cover an area of the photoconductor in the range of 10 to 60%.

An electrophotographic apparatus, comprising:

• a charging unit configured to charge an electrophotographic photoconductor,
• an exposing unit configured to expose the charged electrophotographic photoconductor to a recording light to form an electrostatic latent image,
• a developing unit configured to develop the electrostatic latent image by means of a developing agent to form a toner image, and
• a transferring unit configured to transfer the toner image onto a transfer material,
• wherein the electrophotographic photoconductor comprises
• a photoconductive layer, and
• a conductive support, and
• 20% by volume to 60% by volume of fine particles of fluorine-contained resin and at least one compound selected from the group consisting of amine aromatic compounds and hydroxy aromatic compounds are incorporated into the outermost layer of the photoconductive layer;
