Image forming apparatus

Image Number 3 for United States Patent #8131172.

An image forming apparatus is provided. The image forming apparatus includes an accommodating member configured to accommodate developer; a supply member configured to supply the developer of the accommodating member; a developer holding member configured to supply the developer from the supply member to an image holding member; and a voltage controller configured to apply a first predetermined voltage to the supply member and apply a second predetermined voltage to the developer holding member so as to supply the developer from the accommodating member to the electrostatic latent image formed on the image holding member through the supply member and the developer holding member. The voltage controller, when starting to apply a voltage to the supply member, applies an excessive voltage to the supply member, the excessive voltage having a polarity same as the first predetermined voltage and being larger in an absolute value than the first predetermined voltage.
