PURPOSE:To miniaturize a device by arranging an outer rotor type driving motor, which rotates a photoreceptor drum, inside of the drum and by using part of the drum as the external wall of the outer rotor of the driving motor. CONSTITUTION:Along the outer circumference of photoreceptor drum 1, charging corona discharging means 2, optical means 3, developing means 6, transfer means 9, cleaning means 16, and discharging corona discharging means 18 are provided successively adjoining to the photoreceptor. At the botton of drum 1, a paper feeding and ejecting path for copying paper 10 is provided. As motor 19' driving drum 1, the outer rotor type one having rotor 26 at the outer circumerence of stator 25 is used, and while this motor 19' is installed in drum 1, the external wall of the outer rotor is composed of part of drum 1. |
