Therefore, when conveying A3-size recording paper at the conveying speed of A4-size recording paper, for example, the paper length of A3-size recording paper is longer than that of A4-size recording paper. If it is too curved, the recording paper will still bend into waves between the transfer roller and the discharge roller

Abstract

To provide an image forming apparatus wherein paper jamming is prevented, and an ejected recording paper is also prevented from being wavy.A multi-functioned machine 1 is provided with: a paper size prescribing part 111 for prescribing at least a paper size of a recording paper; a transporting speed setting part 112 for setting a transporting speed of a fixing roller in the transfer device side and that of an eject roller in the discharge port side; a fixing roller driving part 1311 for driving the fixing roller at the transporting speed of the fixing roller which is set by the transporting speed setting part 112; and an eject roller driving part 1312 for driving the eject roller at the transporting speed of the eject roller which is set by the transporting speed setting part 112. The transporting speed setting part 112 makes the transporting speed of the fixing roller higher than that of the eject roller and sets a speed difference between the transporting speed of the fixing roller and that of the eject roller in accordance with the paper size of the recording paper which is prescribed by the paper size prescribing part 111.

Description

technical field [0001] The present invention relates to an image forming apparatus comprising a transfer device for transferring a toner image onto recording paper and a discharge port for discharging the recording paper conveyed from the transfer device to the outside of the device. At least 2 rollers. Background technique [0002] Generally, in image forming apparatuses such as printers and copiers, a photosensitive drum constitutes an image forming unit that is commonly used. In such an image forming apparatus, an electrostatic area is formed on the surface of a photosensitive drum by a charging section, and an electrostatic latent image based on image data is formed on the electrostatic area by laser light irradiated from an exposing section, etc. The image is developed as a toner image. Then, the toner image is transferred to the recording paper by the transfer unit, and the toner remaining on the surface of the photosensitive drum is remov...
