摘要:
In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a transfer paper sheet, the toner on the transfer paper sheet is heated to be melted or softened. An offset belt having adhesive force stronger than that between the transfer paper sheet and the toner comes in contact with the toner. The toner is separated and removed from the transfer paper sheet when the offset belt and the transfer paper sheet are separated from each other. Heating of the toner is maintained until the transfer paper sheet is separated from the offset belt. The transfer paper sheet is separated from the offset belt before the toner is cooled and solidified. A toner heating maintaining device is constructed by using a heating-supporting member having a heater therein and arranged such that the transfer paper sheet and the offset belt are supported between the heating-supporting member and a heating roller. The heating-supporting member has a bent portion on a downstream side in a conveying direction of the transfer paper sheet.
