Patent ID: 8849149

Claim:
An image forming apparatus comprising: a photo conductor; a charging device configured to charge a surface of the photo conductor; an exposure device configured to expose the charged surface of the photo conductor and to form an electrostatic image thereon; a developing device configured to attach toner to the electrostatic image and to develop the electrostatic image as a toner image; a plurality of temperature measuring devices, each configured to measure a temperature at a different location; and a control device configured to divide the photo conductor into a plurality of regions of which the number is greater than that of the temperature measuring devices, and individually set, for each region, an exposure condition for exposure performed by the exposure device, wherein in a case where there are differences in values among the measured temperatures measured by the plurality of temperature measuring devices, the control device calculates a temperature in each of the plurality of regions based on the values of the temperatures, and individually sets the exposure condition for each region based on the temperature calculated for the region.
