A sheet processing apparatus that performs processing for sheets such as sorting or stapling of the sheets after image formation includes a motor that controls a rotating position of a sheet pushing member. When a leading end of a sheet passes, after the leading end of the sheet reaches a pivoting roller, a rotating position of the sheet pushing member is controlled according to a conveyance condition during the passage of a trailing end of the sheet. The sheet pushing member is rotated and, when the trailing end of the sheet passes, the sheet is conveyed while a charge removing brush is pressed against the sheet.
