Abstract

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.

Claims (13)

1. An image forming apparatus, comprising:

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 is configured to abrade part of the surface layer of the transfer member when the abrading member contacts the transfer member,

wherein the abrading member abrades the deteriorated fluorocarbon resin dispersion layer at the surface of the transfer member, and a new fluorocarbon resin dispersion layer is exposed to the surface of the member.

2. The image forming apparatus according to claim 1 , further comprising:

a detector that detects a degree of the second transfer of the toner image from the transfer member to the recording medium,

wherein the abrading member contacts the transfer member in accordance with the detected degree of the second transfer.

3. The image forming apparatus according to claim 1 , further comprising a charge applying portion that applies a charge to the toner such that a change in the degree of the second transfer as a result of deterioration of the toner is reduced.

4. The image forming apparatus according to claim 1 , wherein the abrading member is positioned downstream from the second transfer device.
