Patent ID: 8655210

Claim:
An image forming apparatus comprising: an image bearing member configured to bear a latent image; a development apparatus which develops the latent image formed on the image bearing member with toner; a transfer apparatus which transfers the toner image formed on the image bearing member to a transfer material; a cleaning apparatus which contacts with the image bearing member and cleans toner remaining on the image bearing member; an input portion to which information for smoothness of the transfer material onto which the toner image is transferred is inputted; and a controller configured to control a potential difference between a non-image portion potential of the image bearing member and a direct current component potential of a bias applied to the development apparatus at the time of forming the toner image based on the information inputted to the input portion, the controller controlling to decrease the potential difference in a case that the information inputted to the input portion is equal to or higher than a predetermined smoothness as compared to a case of being lower than the predetermined smoothness.
