<p>PROBLEM TO BE SOLVED: To provide a 4 cycle type image forming apparatus by which a color image of high quality can be obtained by keeping down unevenness in image density generated by unevenness in light quantity in a solid-state scanner type exposure device. SOLUTION: In an exposure correcting part 26, multiple correction data (correction data A and B) are stored to control the unevenness in light quantity in an LED array 25 of the exposure device 13. Then, the correction data by which the unevenness of light quantity can be best controlled is selected for each color and the exposure value for each light emitting element in the LED array 25 is corrected based on the selected correction data in the exposure correcting part 26.</p> |
