Abstract: An image forming substance removing apparatus for preventing an unstabilizing liquid from being excessively applied to a sheet material unnecessarily, preventing a bad state of transporting the sheet material, and not requiring a long time for drying the sheet material is provided. In the above-mentioned apparatus, an unstabilizing liquid supplying unit applies the unstabilizing liquid to the transfer material and is constructed with an applying roller for pumping up the unstabilizing liquid by an action of its rotation, a restriction roller for bringing the applying roller into contact with the transfer paper, and others. And further, in order to move the restriction roller between a position of coming into contact with the applying roller and a position of departing therefrom, a tip end sensor for sensing the tip end of the transfer paper, a spring, and a solenoid, etc. are provided in the apparatus.

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.

Abstract: A copying method for producing duplicates of an original of at least two colors by using a composite photosensitive member including more than two photosensitive layers, wherein the photosensitive member is subjected to charging more than twice and exposed to an optical image of the original more than once by changing charging and exposing conditions, to vary charge carried on the surface and in the interior of the photosensitive member. This causes two types of electrostatic image to be formed on the surface of the photosensitive member; one type includes image regions having a positive surface potential, a negative surface potential and a substantially zero surface potential respectively and the other type includes two image regions having different surface potentials of same polarity respectively, and one image regions of substantially zero surface potential, depending on differences in color between image regions of the original corresponding to the image regions on the photosensitive member.
