Abstract
An image forming apparatus includes an image forming unit composed with a photosensitive body, a cleaning part, a charging part, and a development part, an exposure part, a control part, a sensor, a voltage application part and an exposure control part. Wherein in a state where the exposure part is suspended in order not to form an electrostatic latent image, the control part applies a charging voltage, a development voltage, and a transfer voltage, and afterwards executes a light exposure detection process using the sensor, and if a developer image of threshold, which indicates that a light exposure occurred, is detected, the control part executes a cleaning sequence of the photosensitive body using the cleaning part.
