ABSTRACT:
A sheet feeding device avoiding diagonal feeding of a sheet for use in an image forming apparatus. The image forming apparatus includes a sheet cassette and a sheet supply roller unit positioned deviatedly with respect to a widthwise center of the cassette. The deviated position of the sheet supply roller provides rotational force to the sheet for causing diagonal feeding thereof. The sheet feeding device includes a plurality of feed rollers arrayed side by side in the widthwise direction of the sheet. One feed roller positioned close to the sheet supply roller unit provides the sheet feeding force greater than that of the remaining sheet feed roller positioned far away from the sheet supply roller for providing a linear relationship between a resultant sheet feeding force and a resultant resistive force in a direction parallel with the sheet feeding direction. The difference in sheet feeding force is provided by changing nipping pressure of the feed rollers, friction coefficient thereof, or peripheral speed thereof.
