Abstract:
An image forming apparatus comprising:an image carrier rotatively driven;charging means for uniformly charging a surface of the image carrier;image exposing means for forming an electrostatic latent image on the surface of the image carrier on which the charging means uniformly charges, by exposing the surface according to image information;developing means for developing a toner image from the electrostatic latent image formed by the image exposing means;transferring means for transferring the toner image formed on the surface of the image carrier by the developing means onto a transfer material;cleaning means for contacting to the surface of the image carrier to remove residual toner remaining on the surface of the image carrier after the toner image formed on the surface of the image carrier is transferred onto the transfer material by the transferring means;measuring means for measuring a surface roughness or physical property value reflecting the surface roughness of the image carrier;surface correction toner image forming means for forming a toner image extending in parallel to a direction of a rotation axis of the image carrier at a non-image area on the surface of the image carrier, the surface correction toner image forming means is incorporated in the developing means; anda controller for changing a formation condition of the surface correction toner image formed parallel to the direction of the rotation axis of the image carrier at the non-image area on the surface of the image carrier by the surface correction toner image forming means, according to the surface roughness or the physical property value reflecting the surface roughness of the image carrier measured by the measuring means.
