Sheet feeding apparatus and image forming apparatus

An image forming apparatus comprising:

• an image formation unit configured to form an image on a sheet;
• a sheet stacking plate on which sheets are to be stacked;
• a cassette main body configured to support the sheet stacking plate;
• a regulating device disposed at the cassette main body to be movable in a first direction and movable in a second direction opposite to the first direction, and configured to regulate an end position of the sheets;
• a plurality of first engaged portions disposed at the cassette main body in a moving direction in which the regulating device is configured to move;
• and
• a plurality of second engaged portions disposed at the cassette main body in the moving direction of the regulating device, wherein the plurality of second engaged portions are arranged at positions separated from the plurality of first engaged portions with respect to a direction intersecting the moving direction of the regulating device;
• wherein the regulating device includes:
• a holding member,
• a lever disposed rotatably at the holding member and configured to be operated,
• an elastic member,
• a first engaging portion configured to be urged by the elastic member to engage with the plurality of first engaged portions,
• a second engaging portion movable in a vertical direction and configured to engage with the plurality of second engaged portions, and
• an urging portion provided at the lever and configured to urge the second engaging portion,
• wherein, as seen from an axial direction intersecting the moving direction of the regulating device in a state in which the second engaging portion engages with a second engaged portion, the urging portion is disposed between a first surface of the lever and a second surface of the lever opposite to first surface with respect to the moving direction, and the urging portion is disposed completely above the elastic member, and
• wherein a rotational movement of the lever moves the second engaging portion upward by the urging portion in a state in which the first engaging portion engages with the first engaged portion by the elastic member.
