ABSTRACT:
An image forming apparatus includes a static electricity eliminator to remove residual charge from a printing medium. A selector is provided to connect the static electricity eliminator to ground through a selected resistance, and a controller is provided to control the selector depending on printing medium characteristics. The resistance in the ground path connected to the static electricity eliminator is changed according to printing medium characteristics such that elimination of residual charge is effective over a range of printing media having different printing medium characteristics.
