When the paper passes the transfer roller, the developed image is transferred to the paper. When an image is transferred from the photosensitive drum to a sheet, the image is attracted to the sheet and is not fixed. When paper passes between the fixing roller and the pressure roller, the paper is dried by the heating electrode in the fixing roller and squeezed by the pressure roller, so that the toner melts and permeates into the paper fibers to form a record which can be permanently preserved, and finally the residual toner is cleaned.
