Sheet conveyance apparatus and image forming apparatus

A sheet conveyance apparatus comprising:

• a conveyance rotating member pair configured to convey a sheet in a sheet conveyance direction;
• a skew correction portion including a first rotating member pair having a first nip against which a leading edge of the sheet conveyed by the conveyance rotating member pair abuts, and a second rotating member pair disposed at a position different from the first rotating member pair in a width direction orthogonal to the sheet conveyance direction and having a second nip, the leading edge of the sheet abutting against the first nip and the second nip in a case where a skew of the sheet is corrected;
• and
• a guide portion that guides the sheet conveyed by the conveyance rotating member pair toward the first nip and the second nip,
• wherein the guide portion includes:
• a guide surface that forms a conveyance path through which a sheet passes;
• and
• a recess portion that is formed at the guide portion and disposed upstream of the first nip and the second nip in the sheet conveyance direction and between the first nip and the second nip in the width direction, and is recessed to an opposite side to the conveyance path with respect to the guide surface, and
• wherein the recess portion is configured such that, in operation of the sheet conveyance apparatus, a leading edge, abutting against the first nip and the second nip, of the sheet conveyed by the conveyance rotating member pair enters the recess portion.

A sheet conveyance apparatus comprising:

• a conveyance rotating member pair configured to convey a sheet in a sheet conveyance direction;
• a skew correction portion including an abutment surface, a leading edge of the sheet conveyed by the conveyance rotating member pair abutting against the abutment surface in a case where a skew of the sheet is corrected;
• and
• a guide portion that guides the sheet conveyed by the conveyance rotating member pair toward the abutment surface,
• wherein the abutment surface includes a root portion,
• wherein the guide portion includes:
• a first guide surface that is disposed on a first side with respect to the abutment surface in a width direction orthogonal to the sheet conveyance direction and forms a conveyance path through which the sheet passes;
• a second guide surface that is disposed on a second side with respect to the abutment surface in the width direction and forms the conveyance path;
• and
• a recess portion that is formed at the guide portion and disposed upstream of the abutment surface in the sheet conveyance direction, is disposed at a position overlapping with the abutment surface in the width direction, and is recessed to an opposite side to the conveyance path with respect to the first guide surface and the second guide surface, and
• wherein the root portion is positioned within the recess portion such that the leading edge of the sheet enters the recess portion upon abutting against the abutment surface.
