Abstract
The present invention provides a sheet feeder and an image forming apparatus that can prevent a sheet from being broken, bent, or remaining in an apparatus when a sheet containing portion is pulled out. In association with a cassette pulling operation, a separation mechanism separates a separation roller that is brought into press-contact with a feed roller in a manner in or out of contact with the feed roller, and lowers a lifter plate. A restricting portion constituted of a feed roller separation arm and a feed roller separation spring restricts the feed roller being applied a force by a feed roller pressurizing spring from following the separation roller separated from the feed roller and the lowering lifter plate when the cassette is pulled out.
