  • Method of and an apparatus for removing image forming substance from an image supporting body
    Patent number: 6080255
    Abstract: In a toner removing apparatus in which, after toner attached to transferring paper is heated and adheres to a peeling-off belt, transferring paper is separated from the belt and thereby toner is peeled off from transferring paper, the peeling-off belt is cooled by a cooling fan and thereafter toner is removed therefrom. The transferring paper is tightly attached to the peeling-off belt, and a cleaning fan is provided so as to oppose to the peeling-off belt passing through the pressurizing portions of upper and lower heating rollers for heating the belt and moving to the cleaning portion in the belt cleaning apparatus. The temperature of toner is lowered in order to harden toner to an extent that the condensation of the image forming substance sticking on the peeling-off belt turns out to be larger than the sticking force between the image forming substance and the peeling-off belt member.
