PURPOSE:To prevent from reversely polarized electrification and to attain even electrification of an image carrier by providing a phase shifting transformer varying a phase of a voltage ripple wave form, in a power source supply circuit of a destaticizing needle. CONSTITUTION:After a photosensitive body 1 is destaticized with light from a lightening, it is charged negative with a primary electrifier. Next the photosensitive body 1 reaches an image exposure part. The light being irradiated from the lighting is reflected on an original surface and the image is formed on the photosensitive body 1 surface by a short focus small diameter image formation element array and is exposed. A toner image of the photosensitive body 1 side is successively transferred by a transfer discharger 6 to the paper carried while synchronized to the toner image. By the electric field formed with the curvature of the photosensitive body 1 and the destaticizing needle 7 it is separated from the photosensitive body 1 and it is carried to the fixing device of the toner image. In thus case a phase converter 14 is built in the power source supply circuit of the destaticizing needle 7 and a larger portion of the absolute value of the voltage waveform at transfer and destaticization is shifted 180 deg., so the potential difference does not change greatly. |
