<p>PURPOSE:To prevent occurrence of a trace of a paper feed roller and a support roller trace so as to obtain a satisfactory image transferability by making the axial length of the paper feed roller equal to or greater than the maximum printing width of a sheet material so that the charge is made uniformly over the entire surface of the sheet material. CONSTITUTION:Upon paper feeding, a sheet material 1 is taken out from a stacking means 2 through one revolution of a completely perfect circular section of a paper feed roller 4, and after the paper feed roller 4 being stopped, the roller and the separating pad 7 are separated from each other while the sheet material 1 is clamped between an idler roller and the separating pad 7. In this arrangement, the axial length of the paper feed roller 4 is made to be equal to or greater than the maximum printing width L1 of the sheet material 1.</p> |
