Patent ID: 8554096

Claim:
An image forming apparatus having an image bearing member, a charging unit configured to charge the image bearing member, a latent image forming unit configured to form an electrostatic latent image on the image bearing member charged by the charging unit, and a development unit configured to develop the electrostatic latent image formed on the image bearing member by a developer, the image forming apparatus comprising: a charging voltage generation unit configured to generate a charging voltage to be applied to the charging unit; a developing voltage generation unit configured to generate a developing voltage to be applied to the development unit, the developing voltage generation unit including a driving part for driving the developing voltage generation unit according to a setting signal to be input; and a correction unit configured to change the output from the developing voltage generation unit in conjunction with a change of an output from the charging voltage generation unit, wherein the correction unit is connected to a voltage output part of the charging voltage generation unit and the driving part of the developing voltage generation unit.
