Abstract:
1. An image forming apparatus comprising: an electrophotographic photoreceptor having an outermost layer configured to comprise at least a cured product including a charge transporting skeleton; a charging unit that charges the electrophotographic photoreceptor; an electrostatic latent image forming unit that forms an electrostatic latent image at the charged electrophotographic photoreceptor; a developing unit that develops the electrostatic latent image formed at the electrophotographic photoreceptor by a developer to form a toner image, the developing unit storing a developer comprising a toner having toner particles including a crystalline resin and having a shape factor SF1 of from about 100 to about 150 in addition to a volume average particle diameter of from about 3 μm to about 6 μm, and fluorocarbon-based resin particles as an external additive; a transfer unit that transfers the toner image to a medium to be transferred; and a cleaning unit that cleans a surface of the electrophotographic photoreceptor with a blade comprising urethane rubber, the blade disposed applying a pressure to the electrophotographic photoreceptor surface of about 0.20 mN/mm or more, wherein: the charge transporting skeleton is derived from a nitrogen-containing compound selected from the group consisting of a triarylamine-based compound, a benzidine-based compound and a hydrazone-based compound, and the nitrogen-containing compound is represented by the following Formula (A): wherein, in Formula (A), each of Ar wherein the chain polymerizable functional group comprises four or more methacryloyl groups.
