Title: Fixing device
Inventor: TAKADA SHIGEAKI
IPC: G03G15/20
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To effectively remove residual toner stuck to a pressure roller and to prevent a deterioration of image caused by staining on a recording material with the residual toner by making the surface of a cleaning means rough. SOLUTION: A cleaning roller 13 has such projecting and recessing parts (rough surface) that the surface in contact with the pressure roller 9 of an aluminum roller is processed by blasting. Thus, the surface area of the roller 13 is made larger to make the heat radiation of the roller 13 effective and even if a fixing temp. is raised or low-melting-point toner is used to increase the speed of a device and improve fixability, the melted toner remaining on the surface of the pressure roller 9 is brought into contact with the roller 13 to be cooled/solidified/stuck to the roller 13, so that the pressure roller 9 is cleaned. Since the surface area is made larger, the sticking force of the roller 13 and the toner stuck thereon becomes greater and the stuck toner can be prevented from peeling off and returning to the pressure roller 9 again.
