Abstract
An image forming apparatus includes a photosensitive body, a charge wire disposed along the photosensitive body at a specified spacing from the photosensitive body and adapted for charging the photosensitive body, the charge wire being tiltable on a plane passing an entirety of the charge wire and perpendicularly intersecting a surface of the photosensitive body. This apparatus is provided with a detector for detecting an image density distribution in a main scanning direction of copy paper, tilt angle calculator for calculating, based on a detected image density distribution, a correcting tilt angle of the charge wire to obtain a desired image density distribution in the main scanning direction, and a tilt angle controller for controlling the tilt angle in accordance with a calculated correcting tilt angle.
