A sheet feeding device for use in an apparatus body of an image forming apparatus may include a sheet holder configured to be removed from and attached to the apparatus body and to hold a stack of sheets therein; an actuator including a base portion pivotally attached to the apparatus body via a first shaft and a movable portion pivotally attached to the base portion via a second shaft and extending toward the sheet holder; and a detector configured to detect a position of the base portion. The actuator may be configured such that the base portion and the movable portion pivot in response to the detector detecting the position of the base portion. The movable portion may be configured to pivot in a removal direction in which the sheet holder is removed from the apparatus body.
