Image forming apparatus with increased heat dissipation structure

An image forming apparatus comprising:

• an image carrier belt for carrying an electrostatic latent image;
• a developing roller to be brought into contact with the image carrier belt for supplying a nonmagnetic mono-component developer to the electrostatic latent image carried by the image carrier belt, thereby forming a developer image;
• a thickness-limiting roller kept in contact with the developing roller for limiting, to a predetermined value, a thickness of the developer provided on the developing roller;
• and
• a transfer unit for transferring the developer image, carried by the image carrier belt, onto an image transfer medium,
• wherein the image carrier belt, the developing roller and the thickness-limiting roller are each made of a metal.
