摘要： A feeding device includes a stacking member, a raising device, a feeding member, an interlocking device including a sheet contact portion, a switching device, a holding member, and a movement device. The feeding member is movable between contact and retracting positions, and rotates in contact with a sheet stacked on the stacking member in a state of being located at the contact position. The sheet contact portion contacts the stacked sheet, and moves by being pressed against the stacked sheet where the raising device raises the stacking member. The switching device switches the raising device between a permitted state and a regulated state. The movement device moves the feeding member to the retracting position above the contact position by moving the holding member. The raising device does not change from the regulated state to the permitted state when the movement device moves the feeding member to the retracting position.

摘要： A feeding apparatus and an image forming apparatus capable of reducing malfunctions due to wear of a portion where a sheet surface detection member makes contact with a sheet, and stably providing favorable feeding performance are provided. The feeding apparatus includes a holder configured to hold a first lever and a feed roller. The first lever includes a sheet contact portion configured to make contact with a sheet stacked on a sheet stacker. The feed roller, the first lever, and the holder are configured to be integrally detachable from a main body of the feeding apparatus.
