Abstract

PURPOSE:To prevent the occurrence of difference in transfer efficiency in the same image forming process by supplying a transfer current and a destaticizing current in a specified timing before a transfer material is supplied to a transfer position by a transfer material carrier means. CONSTITUTION:Before the transfer sheet is supplied to the transfer material carrier sheet 501 at latest, the supply of the transfer current to a transfer electri fier 5b constituting a transfer means and the supply of the destaticizing current to an internal electrifier 5d and an external electrifier are started by a CPU in a control unit in a specified timing. In such a constitution, the surface poten tial of the sheet 501 at the time of using the transfer sheet of the standard size of A4 is made uniform all over the area if the transfer electrifier 5b is redriven in the above-mentioned way. Then, the surface potential the sheet 501 is made uniform if the external electrifier and the internal electrifier 5d are driven. Since the surface potential of the sheet 501 at the time of executing an image formation by using the transfer sheet of the standard size of A3 after the size of A4 becomes uniform, the difference in the transfer efficiency does not occur.
