A sheet feeding device, which is included in an image forming apparatus, includes a sheet container to accommodate a recording medium, a sheet feeding body to press a surface of the recording medium in the sheet container and feed the recording medium in a sheet conveying direction, a pair of sheet position regulators to regulate a position of the recording medium in a sheet width direction perpendicular to the sheet conveying direction, and a load applier to contact the surface of the recording medium and apply a load to the recording medium at the surface. The recording medium is brought to move toward one of the pair of sheet position regulators while the recording medium is being fed. A lower face position in a standby state of the sheet feeding body is lower than a lower face position in a standby state of the load applier.

In accordance with one embodiment, an image forming apparatus comprises a cassette for paper feed configured to contain a tray capable of stacking papers stored in a packaging member of which one end portion is opened, together with the packaging member; a paper feed section configured to contain a pickup roller which picks up the papers stored in the packaging member from the opened end portion of the packaging member; a regulating member configured to regulate that the packaging member is conveyed from the tray of the cassette; and a protrusion configured to be formed and protrude from the regulating member to cover the opened end portion of the packaging member.
