Patent ID: 7343111

Claim:
An electrophotographic image forming apparatus for forming toner image onto a recording material comprising: a photoconductor; an electrostatic charger to charge the photoconductor at an electrostatic potential; an exposing device to form an electrostatic latent image on the photoconductor by exposing the charged photoconductor; a developing device to develop the electrostatic latent image on the photoconductor with toner by applying a development bias so as to form a toner image; a transferring device to transfer the formed toner image onto a recording material; a fixing device to fix the toner image on the recording material; and a controller to control the electrostatic potential, the controller controlling a difference between the electrostatic potential and developing bias to be higher in the case that glossiness of the recording material is high than in the case that glossiness of the recording material is low.
