PURPOSE:To improve the transfer characteristic of a sensible image and to suppress an image memory by specifying the wavelength light of a main eraser and pre-transfer eraser and the energy distribution ratio of the wavelength light. CONSTITUTION:A light source which consists essentially of 500-700nm wavelength light and has >=30% and <=60% energy distribution ratio of >=600nm wavelength light is used as the main eraser 3. A light source which consists essentially of >=600nm wavelength light and has <=30% energy distribution ratio of >=600nm wavelength light is used as the pre-transfer erase 23. The electrons which are well infiltered and trapped into a photosensitive layer are thereby effectively released to the extent of obviating importation of such photofatigue as to exert influence on the image quality to the photosensitive layer of a photosensitive body. In addition, the potential in the part of the photosensitive layer where a toner rides is sufficiently lowered, by which the transfer efficiency of the sensible image is improved. |
