An image forming apparatus includes an image holding body that holds an electrostatic latent image; a developing device that develops the electrostatic latent image with a toner and forms a toner image on the image holding body; a transfer member having a fluorocarbon resin dispersion layer at least at a surface layer of the transfer member, fluorocarbon resin being dispersed in the fluorocarbon resin dispersion layer; a first transfer device that first-transfers the toner image, which is formed on the image holding body, on the transfer member; a second transfer device that second-transfers the toner image, which is first-transferred on the transfer member, on a recording medium; and an abrading member that is arranged to come into contact with and be separated from the transfer member and abrades part of the surface layer of the transfer member when the abrading member contacts the transfer member.

Image forming apparatus

An electrophotographic photoreceptor comprising at least a photosensitive layer on an electroconductive substrate, a surface layer of the electrophotographic photoreceptor including a fluorinated alkyl group-containing copolymer having repeating units represented by the following formulae A and B, and fluorine-based resin particles:  wherein in Formulae A and B, l, m and n each independently represent a integer number of 1 or more; p, q, r and s each independently represent 0 or an integer of 1 or more; t represents an integer of from 1 to 7; R, R, R, and Reach independently represent a hydrogen atom or an alkyl group; X represents an alkylene chain, a halogen-substituted alkylene chain, &#x2014;S&#x2014;, &#x2014;O&#x2014;, &#x2014;NH&#x2014; or a single bond; Y represents an alkylene chain, a halogen-substituted alkylene chain, &#x2014;(CH(OH))&#x2014; or a single bond; and z represents an integer of 1 or more.
