SHEET AFTER-TREATING DEVICE, SHEET CONTAINING DEVICE, AND IMAGE FORMING DEVICE HAVING THE DEVICES

摘要

PURPOSE: To provide a sheet after-treating device to contain paper sheets in such a state to prevent curling of a paper sheet after an image is formed. CONSTITUTION: Paper sheets S discharged after an inmate is formed are conveyed through a sort pass 6a and contained in bin trays b1-b5. Heat generating bodies 10 are arranged at the sort pass 6a and the pin trays b1-b5 to heat a discharge paper. This constitution prevents the occurrence of phenomenon wherein the paper sheet is curled as a result of a toner image on the paper sheet being contracted during cooling, the decrease of a containing amount of the paper sheets due to the phenomenon, and the occurrence of defecting matching.
