Abstract:
The present invention provides an image forming apparatus which is equipped with at least a latent electrostatic image forming unit, a developing unit, a transferring unit, and a fixing unit, wherein the transferring unit is configured to apply a positive electric potential to a visible image formed on the latent electrostatic image bearing member via a recording medium, the latent electrostatic image member has a surface layer which comprises a hardened material hardened by irradiating at least a trifunctional or more radical polymerizable compound having no charge transporting structure, a radical polymerizable compound having a charge transporting structure, and a reactive silicone compound having any one of an acryloyloxy group and a methacryloyloxy group, and the concentration of the reactive silicone compound is varied in between the surface part and the innerlayer part of the surface layer.
