Image forming system and sheet conveyance apparatus

A sheet conveyance apparatus that receives and conveys a sheet conveyed by a conveyance member that conveys the sheet in a predetermined conveyance direction, the sheet conveyance apparatus comprising:

• an endless conveyor belt having a conveyance surface extending in the predetermined conveyance direction and configured to convey the sheet delivered from the conveyance member to the conveyance surface in the predetermined conveyance direction;
• a plurality of rotary members arranged in the predetermined conveyance direction at positions facing the conveyance surface, and configured to rotate at least in the predetermined conveyance direction while nipping the sheet with the conveyance surface;
• a regulation portion having a contact portion configured to come into contact with a side edge that is an edge of the sheet in a sheet width direction, and configured to regulate movement of the sheet in the sheet width direction beyond the contact portion in a case where the side edge of the sheet comes into contact with the contact portion, the sheet being conveyed using the conveyor belt and the rotary members, the sheet width direction being a direction intersecting the predetermined conveyance direction;
• a load changing unit configured to change a load applied from at least some of the plurality of rotary members to the sheet;
• a sheet information recognition unit configured to recognize information regarding the sheet to be conveyed;
• and
• a control unit configured to control the load changing unit, wherein
• the conveyor belt and the plurality of rotary members are configured to allow the sheet to move in the direction intersecting the predetermined conveyance direction in a case where the regulation portion comes into contact with the side edge of the sheet in a state where the sheet is conveyed in the predetermined conveyance direction by the conveyor belt and the plurality of rotary members, and
• the control unit is configured to control the load changing unit according to the information regarding the sheet recognized by the sheet information recognition unit.
