Abstract
A feeding apparatus for print media comprises a pressure roller that is provided at an upstream side of an image forming section in a feeding direction of the print media and rotates with being pressed onto an upper surface of a feeding path. The pressure roller includes a plurality of unit rollers aligned along a primary sweeping direction perpendicular to the feeding direction. A center unit roller of the unit rollers is made wider than other unit rollers in the primary sweeping direction. According to the apparatus, cocklings on print media can be removed at desired portions with a simple configuration by controlling suction forces due to varying relative positions to suction ports. Therefore, flatten state of print media in the image forming section can be easily ensured.
