Abstract

PURPOSE:To make the transfer efficiency in respective transfers maximum in case of plural times of transfer and to reduce the optical attenuation of a photosensitive body by irradiating the photosensitive body with a light whose wavelength is changed according to the spectral reflection characteristic of toner before transfer and executing destaticization. CONSTITUTION:A pretransfer destaticizing lamp 18 which irradiates the photosensitive body 4 with the light beam before transferring is installed by utilizing a free space and a filter 19 is interposed between the pretransfer destaticizing lamp 18 and the photosensitive body 4. Just before a developed image on the photosensitive body 4 is transferred on a transfer sheet 8 with the action of a transfer charger 15, the pretransfer destaticizing lamp 18 irradiates the photosensitive body 4 with the light through the filter 19 and the electric potential of the photosensitive body 4 before transferring can be lowered. Thus, the transfer efficiency at every color can be made maximum and the optical attenuation of the photosensitive body can be reduced by selecting colors at every color.
