ABSTRACT:
A transfer plate which also serves as a sheet guide plate is pushed by a torsion spring. A minimum gap less than 0.2 mm between a guide surface of the transfer plate and the surface of a photoreceptor drum is maintained to be smaller than the thickness of a transfer sheet by a spacer member provided on the guide surface. When the sheet passes through the gap between the drum surface and the guide surface, the transfer plate is pushed down by the sheet and the sheet is pressed onto a toner image formed on the drum surface with an appropriate pressure by the pushing force of the torsion spring. At this time, a transfer voltage is applied to the transfer plate, so that the toner image on the drum surface is transferred to the sheet.
