Abstract
A sheet feeding device includes a raising and lowering portion, a first detecting portion, a feeding portion, a second detecting portion, and a controller. When a change in a state of the feeding roller from a state of being in an uppermost sheet feedable position to a state of being not in the uppermost sheet feedable position is detected by the second detecting portion and then a change in a state of the uppermost sheet from a state of being in a feeding position to a state of being not in the feeding position is detected by the first detecting portion, the controller controls the raising and lowering portion to raise the stacking member on the basis of a correction amount determined based on a time from change timing of the second detecting portion to change timing of the first detecting portion.
