Original Abstract Submitted
In a sheet feeding apparatus, a recording material is stacked in a stacking unit, a sheet surface detection member takes on one of a first state, in which the sheet surface detection member displaces according to a height of a top surface of the material, and a second state. A detector detects the sheet surface detection member. A feeding unit is mounted in and removed from a main body. The feeding unit includes a feed roller and a switching unit that switches the sheet surface detection member to one of the first state and the second state. The switching unit switches the sheet surface detection member to the second state in response to the feeding unit being replaced, and a controller detects that the feeding unit has been replaced based on a state change detected by the detector.
