Abstract
In the invention, after the last sheet is conveyed from a paper feed tray, the paper feed tray is lifted up so that the paper feed tray is brought into contact with a suction belt. An elastic cleaning member that removes paper particles, or the like, is installed at an area of the paper feed tray where the paper feed tray is in contact with the suction belt. The suction belt is driven while the cleaning member is in contact with the suction belt. The paper particles, or the like, removed from the suction belt by the cleaning member are collected in a paper-particle collecting device from a vacuum chamber via a vacuum duct.
