ABSTRACT:
An image forming apparatus includes an image carrier on which a static latent image is formed, a main charger to charge the image carrier, an operating portion to direct the output adjustment of the main charger, and a developing device to develop a static latent image by applying developer to it. Further, an image forming apparatus has a charge eliminator arranged between the main charger and the developing device along the rotating direction of the image carrier to fully remove the charge applied to the image carrier through the exposure when the output adjustment of the main charger is directed by the operating portion, and also has a detector to detect the current flowing into the image carrier when the image carrier is charged by the main charger after the output adjustment of the main charger is directed. The detected output of the detector is compared with a reference value, a control value corresponding to an error with the reference value is generated and voltage corresponding to this generated control value is supplied to the main charger.
