PROBLEM TO BE SOLVED: To enable simple and optimum design, while surely ensuring the operation of a device by obtaining a decay reaction time to generate rapid decay in the light decaying characteristic of a photoreceptor and setting the moving time of the photoreceptor from an exposure position to a developing position, in accordance with the decay reaction time. SOLUTION: A toner forming part comprises a photoreceptor drum 1, a charge corotron 2, an exposure means 3, a developing means 4, a cleaning means 5 and a discharge lamp 6. The photoreceptor drum 1 is formed in such a manner that a base material formed in a cylindrical shape out of aluminum is coated with a photosensitive material made of α type copper phthalocyanine and polyester. In other words, the decay reaction time corresponding to the light decay characteristic of the drum 1 is found in consideration of the characteristic of the drum 1. Then, the moving time of the drum 1 from the exposure position to the developing position in a printer is set so as to be more than fixed times the obtained decay reaction time. |
