Abstract:
A transfer method of transferring a toner image formed by developing an electrostatic latent image on a surface of a photosensitive material drum onto a surface of a transfer paper from the surface of said photosensitive material drum, by arranging a transfer roller so as to be opposed to the surface of said photosensitive material drum, maintaining said transfer roller at a potential of a polarity opposite to the polarity of the electric charge of the toner image, and passing the transfer paper in this state through a gap between said transfer roller and said photosensitive material drum; whereina paper powder-removing device comprising a pair of an insulating roller and an electrically conducting roller is provided on a conveyer passage of said transfer paper, and said transfer paper, after having passed through the pair of said rollers, is passed through the gap between said transfer roller and said photosensitive material drum to effect the transfer of toner image;when said electrically conducting roller is arranged on a side opposite to the transfer surface of the transfer paper that passes through the pair of said rollers, said transfer paper is passed in a state where said electrically conducting roller is maintained at a potential of the polarity same as that of said transfer roller; andwhen said electrically conducting roller is arranged on a side of the transfer surface of the transfer paper that passes through the pair of said rollers, said transfer paper is passed in a state where said electrically conducting roller is maintained at a potential of the polarity opposite to that of said transfer roller.
