Sheet conveyor, image forming apparatus having sheet conveyor, and sheet conveying method

摘要

A sheet conveyor includes a first roller and a second roller pressurized to the first roller to hold and convey a sheet, wherein when the sheet is held between the first roller and the second roller, the first roller and second roller are separated at a space equivalent to a thickness of the sheet. The sheet conveyor has a pressurizing delay mechanism configured to bring controllably the first roller and the second roller into contact with each other after the sheet is conveyed from the first roller and the second roller.
