Abstract:
An image forming apparatus includes a developer housing that holds a developer; a lubricant supply brush that rotates when in contact with the developer housing, and that supplies a lubricant to a surface of the developer housing; a lubricant that is in contact with the lubricant supply brush; a first voltage supply unit that supplies an AC voltage on which a DC voltage is superimposed to the lubricant supply brush; a determination unit that determines whether or not a usage state of the developer housing is a state at an initial stage; and a controller that controls the first voltage supply unit to supply the AC voltage on which the DC voltage is superimposed to the lubricant supply brush, prior to start of execution of an image forming operation if the determination unit determines that the usage state of the developer housing is the state at the initial stage.
