Abstract:
An image forming apparatus comprising:a plurality of image forming units, each including an image holding component on which an image for a different color is formed and including a transfer component for transferring the image formed on each image holding component onto a recording sheet at a respective transfer position;a transporter for holding a recording sheet and sequentially transporting the recording sheet to each transfer position of the plurality of image forming units;a first attraction unit which applies attractive force that attaches the recording sheet to a recording sheet supporting surface of the transporter, the first attraction unit being located at upstream side of an image forming unit which is located at a most upstream side in a transporting direction of the recording sheet by the transporter;a second attraction unit which increases the attractive force of the recording sheet which was applied by the first attraction unit, the second attraction unit being located at downstream side of the first attraction unit in the transporting direction of the recording sheet; anda controller which makes only the first attraction unit operative when a first mode is set to form a color image using the plurality of image forming units and makes both of the first attraction unit and the second attraction unit operative when a second mode is set to form a single-color image using only one of the plurality of image forming units.
