摘要： An image forming apparatus comprises a fixing part for fixing a toner image on a transfer material to the transfer material, a conveying part provided on the downstream side of the fixing part, a correcting member provided in a conveyance path leading from the fixing part to the conveying part, for correcting a curl of the transfer material, and a control part for controlling an upstream-side conveyance speed which is a conveyance speed at which the fixing part provided on the upstream side of the correcting member conveys the transfer material and a downstream-side conveyance speed which is a conveyance speed at which the conveying part provided on the downstream side of the correcting member conveys the transfer material. In printing of a first surface in a double-sided printing mode, the control part sets the downstream-side conveyance speed to be larger than the upstream-side conveyance speed. In printing of a second surface in the double-sided printing mode, the control part sets the upstream-side conveyance speed and the downstream-side conveyance speed so that a difference between the upstream-side conveyance speed and the downstream-side conveyance speed is smaller than a difference between the upstream-side conveyance speed and the downstream-side conveyance speed in printing of the first surface.

摘要： The present invention provides an image printing apparatus which comprises registration roller unit which convey an image recording sheet toward an image transfer position at which the toner image is transferred onto the image recording sheet, a sensor which is provided between the registration roller unit and the image transfer position to detect the image recording sheet, and a control unit which controls driving of the registration roller unit. In order to make the time required for each image recording sheet to reach the image transfer position constant, the image printing apparatus is adapted to start the driving of the registration roller unit at the first sheet convey speed higher than the linear speed of the surface of the image carrier, measure the time required until the leading end of a conveyed image recording sheet is detected by the sensor after a driving signal for the registration roller unit is output, and reduce the sheet convey speed of the registration roller unit to the second sheet convey speed at the timing based on the measurement result.
