<p>PURPOSE:To achieve suction of a forward end part of a recording sheet securely at the time of feeding it by setting an electric charge pattern forming range to be a predetermined range from the front part of the recording sheet corresponding to the weight of the recording sheet. CONSTITUTION:An electric charge pattern forming range formed by an electric charge pattern forming means 212 is set to be a range equivalent to the range of a recording sheet sucked and transferred, and this recording sheet is sucked to an endless belt from its forward end to its back end securely to be transferred without peeling. At this time, when the recording sheet is a thin and light paper, an electric charge pattern is formed at a part equivalent to a predetermined range of the front part of the sheet corresponding to its weight, so the recording sheet is held sufficiently to be transferred.</p> |
