    Abstract: Provided are a sheet feeding apparatus and an image forming apparatus, which can set a sheet feeding interval to be short. The controller determines whether a sheet surface height of an uppermost sheet becomes a predetermined sheet surface height, based on a detection signal from a lower limit detection sensor, when a pickup roller abuts the uppermost sheet. When determining that the sheet surface height of the uppermost sheet becomes the predetermined sheet surface height, the controller feeds a predetermined number of sheets without performing detection by the lower limit detection sensor, and then controls a motor such that the uppermost sheet is located with an appropriate range by lifting a tray when feeding a next sheet.

    Abstract: A sheet feeding unit includes a supporting member configured to rotatably support a rotary feeding member, a first retaining member configured to push the supporting member upward from the underside to retain the rotary feeding member at a waiting position, and a second retaining member protruding on the underside of the supporting member when the first retaining member retains the supporting member. The retention of the supporting member by the first retaining member is released in association with the mounting of a sheet storage portion in the mounting position, and then the retention of the supporting member by the second retaining member is released.

    Abstract: A sheet feeding device includes a sheet storage unit, a stacking unit, a raising unit, a sheet detection unit, an attachment detection unit, and a control unit. The sheet storage unit may be attached to and drawn out of an apparatus main body. The stacking unit is raised by the raising unit and is lowered when the sheet storage unit is drawn out. The attachment detection unit detects attachment of the sheet storage unit to the apparatus main body. The control unit determines whether an amount of sheets stacked on the stacking unit exceeds a predetermined amount based on detection results. If the sheet detection unit continues to detect sheets when the sheet storage unit goes from attached, to not attached, to attached to the apparatus main body, the control unit determines that the amount of sheets stacked on the stacking unit does not exceed the predetermined amount.
