Sheet feeding device and image forming apparatus

A sheet feeding device comprising:

• a feeding mechanism having a feeding rotating body that contacts an upper surface of a topmost sheet of a stack of sheets, and configured to execute a feeding process of feeding each sheet from the stack of sheets to a conveying path by rotating the feeding rotating body;
• a displacement mechanism configured to be able to switch between a contact state in which the stack of sheets contacts the feeding rotating body and a separation state in which the stack of sheets is separated from the feeding rotating body by displacing the stack of sheets or the feeding rotating body;
• and
• a return mechanism configured to execute a sheet return process to return, when the displacement mechanism switches from the contact state to the separation state, a positionally deviated sheet among the stack of sheets that has been positionally deviated to a downstream side in the sheet feeding direction with respect to a reference initial position to an upstream side in the sheet feeding direction.
