    摘要： An image forming apparatus including: an electrophotographic photoreceptor; a non-contact charger located close to the electrophotographic photoreceptor, charging the electrophotographic photoreceptor; an irradiator irradiating the electrophotographic photoreceptor to form an electrostatic latent image thereon; an image developer developing the electrostatic latent image with a toner to form a toner image on the electrophotographic photoreceptor; and a transferer transferring the toner image onto a transfer material, wherein the electrophotographic photoreceptor comprises: an electroconductive substrate; a charge generation layer located overlying the electroconductive substrate; a charge transport layer located overlying the charge generation layer; and a crosslinked charge transport layer, located overlying the charge transport layer, wherein the crosslinked charge transport layer is formed by hardening a radical polymeric monomer having three or more functional groups without a charge transport structure and a radical polymeric compound having one functional group with a charge transporting structure.

    摘要： An image forming method including: forming an electrostatic latent image on an image bearing member; developing the latent image with a toner; transferring the toner image onto a receiving material; and fixing the toner image. The image bearing member includes a substrate, and a charge generation layer, a charge transport layer and a crosslinked charge transport layer, wherein the crosslinked charge transport layer includes a compound obtained from radical polymerizable monomers including a monomer having three or more functional groups and no charge transport structure and a monomer having one functional group and a charge transport structure. The toner includes a binder resin, a colorant, and a release agent, wherein tetrahydrofuran-soluble components of the binder resin have a molecular weight distribution such that at least one peak is observed in a range of from 1,000 to 10,000 and the half-width of the molecular weight distribution curve is not greater than 15,000.
