Abstract

PURPOSE:To enable conveying of paper sheets in a sure manner, avoiding contact of transferred surfaces of the sheets with other components of the equipment by conveying the sheets that are being held by a belt at the edges and being hung therefrom. CONSTITUTION:The toner image formed on a peripheral surface of a photosensitive drum 1 is transferred by a transfer charger 9 onto the bottom surface of a paper sheet 8 which is sent from a cassette 22 through rollers 6 and 7. The paper sheets 8 after transferring are adjusted to be straight by a guide bar 10. On the other hand, when a belt 11 which is being moved by pulleys 12 and 14 turns around the pulley 12, slits on the belt gradually open corresponding to differences in the straight moving directions at the curve and changes in angles at the pulley 12. Measuring timing between the paper feeding speed and the driving speed of the belt 11 at the transfer charger 9, a paper sheet is pushed forward to the slit 11a when it is open, and the edge of the sheet is caught by the slit 11a. As the belt 11 changes its shape from flex to straight, following the rotation of the pulley 12, the slit 11a closes, and the paper sheet 8, which is being hung, is conveyed to a fixing device 13.
