Sheet feeding apparatus, and image forming apparatus

A sheet feeding apparatus, comprising:

• a sheet stacking portion on which a sheet is stacked;
• and
• a conveyance portion configured to convey the sheet stacked on the sheet stacking portion,
• wherein the conveyance portion comprises a roller configured to convey the sheet and a shaft supporting the roller,
• wherein the roller can be detached from one end in an axial direction of the shaft along the axial direction, the roller comprising:
• an end surface formed on a downstream end side in a detaching direction which is a direction of detaching the roller;
• an extension portion extending downstream in the detaching direction beyond the end surface;
• an engage portion formed on the extension portion and engageable with the shaft;
• and
• a grip portion extending downstream in the detaching direction beyond the end surface and disposed outside, in a radial direction orthogonal to the axial direction, from the extension portion, and
• wherein an outside surface of the grip portion in the radial direction comprises
• a first edge portion provided at a downstream end of the grip portion in the detaching direction and extending in a circumferential direction of the shaft,
• a second edge portion provided at one end of the grip portion in the circumferential direction, extending in the detaching direction, and connected with the first edge portion, and
• a third edge portion provided at the other end of the grip portion in the circumferential direction, extending in the detaching direction, and connected with the first edge portion,
• wherein the outside surface of the grip portion has only one depressed portion surrounded by the first, second, and third edge portions, and when viewed in the radial direction, the depressed portion is depressed inward in the radial direction relative to the first, second, and third edge portions,
• wherein in a cross-section of the grip portion taken along the axial direction, a length of a bottom surface of the depressed portion in the axial direction is longer than a length of the first edge portion in the axial direction, and
• wherein when viewed in the radial direction, a length of the bottom surface of the depressed portion in the circumferential direction is longer than a length of the second edge portion in the circumferential direction and a length of the third edge portion in the circumferential direction.
