Abstract

An image forming section includes an image bearing body that bears an electrostatic latent. An operation status detecting section detects at least one of an operation status in which the image forming section operates and an environmental condition in which the image forming section operates. The operation status includes, for example, the number of printed pages, the density of toner image, and the amount of toner consumed. A print condition setting section sets preliminary print conditions. The preliminary print condition includes a developing voltage, the amount of light emitted from an exposing unit, and a charging voltage. A limit setting section sets a limit value based on the environmental conditions. A print controller compares the preliminary print condition with the limit value to determine an ultimate print condition so that the ultimate print condition is within a predetermined range.
