PURPOSE:To increase the sensitivity of a photoreceptor with a small amount of electric power as well as to increase the durability with a simple constitution and to ensure the installation of a titled controller in a narrow space, by providing two heater electrodes around rotational center of the photoreceptor and a mobile heater power supply electrode. CONSTITUTION:The heaters 11, 11a and 11b are set equidistantly on the inner circumference surface of a photoreceptor drum 10, and two circular heater electrodes 15 and 16 around a rotation center line 14 are provided on an end surface 10A of the drum 10. At the same time, a heater power supply electrode 19 having terminals 17 and 18 opposite to the electrodes 15 and 16 are supported horizontaly and rockably. The end 20a of a tongue-shaped projection 20 at the opposite side to the terminals 17 and 18 is loosely fitted to an end 21a of an L-shaped arm 21. The arm 21 is always kept turned unticlockwise by the function of a spring 25, and the terminals 17 and 18 contacts with the electrodes 15 and 16. |
