摘要：
An image forming apparatus includes an image bearer, a charger, an exposure device, a developing device, an image density sensor, and a controller. The controller is configured to charge the image bearer, expose the image bearer with a first exposure that saturates potential of the image bearer after exposure to form a latent image pattern on the image bearer, develop the latent image pattern into a toner pattern while changing a developing electrical field, detect a first image density of the toner pattern, determine developing bias and charging bias, form patterns with the first exposure and a second exposure smaller than the first exposure, detect a second image density of the patterns, and determine an exposure to output an image based on the second image density, the first exposure, and the second exposure.
