Abstract
An image forming device is provided that more effectively reduces changes in the image density caused by reductions in the charged potential immediately after the application of charge to a photosensitive body, including: a photosensitive body; a charger that charges the photosensitive body; a charged potential fluctuation prediction unit that predicts an amount of fluctuation in a charged potential of the photosensitive body; an optical scanning device that irradiates the photosensitive body with an exposure laser and forms an electrostatic latent image; a development device that develops the electrostatic latent image; and an exposure laser output correction unit that corrects an output of the exposure laser. The charged potential fluctuation prediction unit predicts an amount of fluctuation in the charged potential from a charging stop time, and the exposure laser output correction unit reduces a change in density of the image caused by a fluctuation in the charged potential.
