Abstract

PURPOSE:To stabilize changing characteristic by arranging that a contactor will not become resistance due to a change in the himidity of the air through organizing the contactor of flexible resistance with a fiber coating a high polymer dispersed with a conductive particle. CONSTITUTION:In order from the image formation position of a light exposure system 7 consisting of a lamp 5, converging light transmission body 6, etc. a developing device 8, a transfer device 9, a cleaning device 10 and a charging device 11 are arranged along the revolving direction of a light sensitive body 4. In the front part of a charger base 24 of the square piller shape in the charging device 11, a polymer 28 is mounted to be removable, and in the front of it, namely, in the side contacting the light sensitive body 4, a contactor 29 having coating formed through immersing a cloth like velveteen in a solvent consists of a high polymer dispersed with a conductive paeticle is mounted. This contactor 29 has no change in the charging characteristic due to changes in the temperature of the air, to which DC voltage and AC voltage from an electrode 30 in the back-side is applied with stability.
