Abstract
An image forming apparatus includes an exposer including an organic electroluminescence element including at least an anode for injecting a hole, a luminescent layer having a luminescent region and a cathode for injecting an electron on a board. A photosensitive member is formed with an electrostatic latent image by exposing light of the exposer, a developer forms a toner image on the photosensitive member by supplying a toner to the electrostatic latent image, and a cooler cools the organic electroluminescence element such that the temperature of the organic electroluminescence element can be controlled.
