Abstract

An image forming apparatus includes a controller that controls rotational driving of a magnetic roller and rotational driving of a developing roller. The controller is capable of performing a toner collecting mode when no image formation is performed. In the toner collecting mode, the magnetic roller and the developing roller are intermittently rotated in a direction reverse to a direction in which the magnetic roller and the developing roller are rotated during image formation, then the magnetic roller is made to rotate in a forward direction, and then, the magnetic roller is rotated in a backward direction.

First claim

What is claimed is:

1. An image forming apparatus comprising:
a developing device configured to develop an electrostatic latent image formed on a surface of an image carrier, the developing device comprising:
a developing container that holds therein a two-component developer containing a toner and a carrier;
a developing roller that feeds the toner to the image carrier, the developing roller being disposed to be opposed to the image carrier by part of an outer circumferential…
