发明名称 Recording apparatus with two charging units for achieving uniform after-transfer zones distribution
摘要 A recording apparatus has a development unit for depositing a toner on an electrostatic latent image on the outer surface of a photosensitive drum while attractively collecting a residual toner on the surface of the photosensitive drum, a transfer charger device for transferring the toner image to a transfer sheet, a conductive brush for uniformalizing a residual toner distribution on the photosensitive drum, after a transfer step has been carried out, and at the same time charging the surface of the photosensitive drum, and a scorotron charger located on the downstream side of the conductive brush, but on the upstream side of the exposure device, and assisting the charging of the drum surface by the conductive brush. The surface of the drum charged by the scorotron charger is exposed by a light beam to provide an electrostatic latent image thereon.
