Abstract

An image forming apparatus includes an image carrier; an exposing unit that exposes the image carrier to light to form an electrostatic latent image on the image carrier; a developing unit that has at least a toner, and develops the electrostatic latent image formed on the image carrier as a toner image; a transfer unit that transfers the toner image onto a recording medium; a fixing unit that fixes the toner image transferred on the recording medium; an exposure-energy modulating unit that modulates exposure energy of the exposing unit; and a development-time detecting unit that detects operation time of the developing unit. The exposure-energy modulating unit modulates the exposure energy based on a result of detection by the development-time detecting unit.
