    摘要: An image forming apparatus comprising: a main body having an image forming section; a sheet feed section having a sheet cassette that accommodates a recording sheet and can be drawn out and loaded to the main body; and a sheet misalignment preventing mechanism that intermittently comes into contact with an uppermost recording sheet in the sheet cassette so as to prevent misalignment of the recording sheet in a loading direction when the sheet cassette drawn out of the main body is reloaded.

    摘要: A paper feeder comprises an acquiring device, a driving roller, driven rollers, a driven roller supporter, a driver, and a controller. The acquiring device acquires thickness information on a sheet of paper. The driving roller rotates by being supplied with torque. The driven rollers rotate with the driving roller when in compressive contact with the driving roller. The driven roller supporter so supports the driven rollers that each of them can rotate under a different rotational load. The driver changes the position of the driven roller supporter relative to the driving roller. The controller selects one of the driven rollers on the basis of the thickness information and so activates the driver as to bring the selected roller into compressive contact with the driving roller.
