Abstract:
1. An image forming apparatus comprising: an image bearing member comprising an electroconductive substrate, a photosensitive layer overlying the electroconductive substrate and a cross-linked resin surface layer overlying the photosensitive layer, the image bearing member configured to bear a latent electrostatic image on a surface thereof; an application device configured to apply a solid lubricant to the image bearing member; a charging device configured to charge the surface of the image bearing member; an irradiation device configured to irradiate the surface of the image bearing member with light to form the latent electrostatic image thereon; a development device configured to develop the latent electrostatic with toner to obtain a developed image; a transfer device configured to transfer the developed image to a recording medium, and; a cleaning device configured to clean the surface of the image bearing member, wherein the cross-linked resin surface layer comprises a cross-linked body of trimethylol propane triacrylate and particulates comprising silicon and an average diameter of agglomeration areas of the particulates comprising silicon on the surface of the cross-linked resin surface layer is from 0.5 to 2.2 μm; wherein an occupation area ratio of the particulates comprising silicon on the surface of the cross-linked resin surface layer is from 2 to 10%; wherein the particulates comprising silicon in the cross-linked resin surface layer are mixed fillers comprising at least two kinds of particulates comprising silicon having a different average particle diameter, particulates comprising silicon having a largest weight % of the mixed fillers has an average particle diameter of from 0.08 to 0.12 μm, and the mixed filler has an average particle diameter of from 0.10 to 0.70 μm; wherein the particulates comprising silicon having the largest weight % of the mixed fillers are hydrophobized amorphous silica; and wherein the at least two kinds of particulates comprising silicon having a different average particle diameter comprise a spherical silica.
