Abstract

PURPOSE:To improve the efficiency of transcription irrespective of environmental humidity by exposing a photoreceptor with spectral sensitive wavelength at the same time as the action of a voltage applying device sucking a powdery toner image to recording paper side. CONSTITUTION:A DC voltage corona charger 26 is provided at the front of a photosensitive drum 10 and a lamp 28 is provided at the back of charger 26 through a green filter 27 which passes only spectral sensitive wavelength. The electric charge which conquers the electrostatic sucking force between the drum 10 and a powder toner image by the charger 26 and charge to suck the toner image is fed to the paper 16. Simultaneously, the drum 10 is exposed by the light of the lamp 28 which passes through the green filter 27 and the statistic sucking force between the drum 10 and a powdery toner image is weakened, sucking the powery toner image on the drum easily on the reporting paper 16. Said constitution makes it possible to weaken the statistic sucking force between the drum 10 and the powdery toner image and suck the powdery toner image statistically in the recording paper, improving the efficiency of transcription.
