A sheet processing apparatus includes a conveyance unit configured to convey a sheet, a stacking portion on which the sheet conveyed by the conveyance unit is stacked, a first regulation member configured to regulate a position of an edge portion, in a conveyance direction, of the sheet stacked on the stacking portion, a second regulation member configured to regulate a position of an edge portion, in a width direction orthogonal to the conveyance direction, of the sheet stacked on the stacking portion, a binding unit supported movably in the conveyance direction and configured to perform a binding process of binding the sheet stacked on the stacking portion, and a moving unit configured to move the second regulation member in the conveyance direction accompanied with a movement, in the conveyance direction, of the binding unit.

A sheet processing apparatus includes a conveyance member to convey a sheet, a pair of alignment members to move relatively in a width direction orthogonal to a conveyance direction of the sheet by the conveyance member, so as to align a position of the sheet in the width direction, and a lower portion to support a lower surface of the sheet between the pair of alignment members in the width direction. In addition, a pair of upper portions are arranged on one side and the other side of the lower portion in the width direction and each hold an upper surface of the sheet, wherein the pair of upper portions is positioned lower than the lower portion in a plane vertical to the conveyance direction.

Sheet processing apparatus and image forming apparatus

A sheet conveyance apparatus includes a receiving conveyance path branching into a first conveyance path and a second conveyance path. A guide member guides a sheet passing through the receiving conveyance path and is movable between a first position to guide the sheet toward the first conveyance path and a second position to guide the sheet toward the second conveyance path. A rotary member is disposed on the receiving conveyance path and configured to guide the sheet by rotating in contact with the sheet. The rotary member guides the sheet on the same side as the guide member that is on the first position, while guiding the sheet on the opposite side from the guide member that is on the second position. The sheet is conveyed in contact with both the rotary member and the guide member when the guide member is at the first position.
