Abstract
Official abstract text for this publication.
Provided are a sheet feeding device and an image forming apparatus for feeding small-size sheets without causing skew and paper jamming. On a downstream side of far-side and near-side side regulating members in a sheet feeding direction, far-side and near-side auxiliary side regulating members are provided so as to be movable in a width direction. When each of sheets has a length capable of being regulated by the far-side and near-side side regulating members in the width direction, the far-side and near-side auxiliary side regulating members are moved to retreat positions. When a sheet has a length shorter than the length capable of being regulated by the far-side and near-side side regulating members in the width direction, the far-side and near-side auxiliary side regulating members are moved to protruding positions, at which they protrude in the width direction with respect to the far-side and near-side side regulating portions.
