Abstract
A sheet forwarding apparatus for supporting a sheet on a transfer drum in a electrophotographic copying machine, onto which a toner image on a photoreceptor drum is transferred, which apparatus includes a pressure roller for pressing the sheet onto the transfer drum while forwarding. An arm member supports the pressure roller and is pivotable around a shaft so as to cause the pressure roller to alternately contact and distance from the transfer drum. An oscillating unit is included for oscillating the arm member, and to apply a constant pressure to the sheet through the pressure roller when the pressure roller is in contact with the transfer drum.
