<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of forming an image of high quality corresponding to the temperature characteristics of a photoreceptor without causing a fall of productivity. <P>SOLUTION: A photoreceptor drum 1 is uniformly charged and exposed while maintaining a regulated temperature using a drum heater 14, and bright part potential VL is measured in each measuring position every 30 mm in a main scanning direction of the photoreceptor drum 1 and every 10°in an auxiliary scanning direction using a potential sensor 4. The distribution of bright part potential VL acquired at the regulated temperature is corrected according to the present temperature of the photoreceptor drum 1 measured using a temperature sensor 11 to find the differential value of bright part potential VL to be corrected in each measuring position, and the amount of exposure is corrected according to the differential value to offset the dispersion of bright part potential VL. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
