ABSTRACT:
A method for xerographic printing, comprises the steps of, holding a part of a work sheet at a position other than a leading end of the work sheet, before the leading end contacts with a toner image forming surface on which a toner image is formed by an electrostatic, charge of toner, holding both surfaces of the leading end of the work sheet and applying a frictional force to at least one of the surfaces of the leading end so that a tension is applied to the work sheet between the held part and the leading end, before the leading end contacts with the toner image forming surface, and making the work sheet contact with the toner image forming surface, and transferring the toner image from the toner image forming surface to the surface of the work sheet by generating an electric field for attracting the charged toner to the surface of the work sheet.
