摘要： An image forming apparatus including a medium storage portion, a supply roller, a conveyance roller, a drive device and a transmission device is provided. The supply roller is rotary driven in a forward direction as a rotating direction to convey the recording mediums to a position for image formation, thereby to supply the abutting uppermost recording medium to a conveyance path. The conveyance roller is rotary driven in a forward direction as a rotating direction to convey the recording mediums to a position for image formation, thereby to allow passage of the uppermost recording medium conveyed by the supply roller. In the image forming apparatus, a conveyance speed of the recording medium by the conveyance roller is adapted to be faster than a conveyance speed of the recording medium by the supply roller.

摘要： This invention is related to a feeder for transporting a print medium from a tray along a U-shaped transporting path. The feeder includes a movement member coupled to a feeding roller. The movement member includes a first portion located at a position such that the print medium makes contact with the first portion when a transporting roller and the feeding roller simultaneously make contact with the print medium. The first portion receives a force from the print medium when the first print medium makes contact with the first portion. The movement member moves the feeding roller by utilizing the force such that a distance between the feeding roller and the support surface of the tray increases.
