Abstract: PROBLEM TO BE SOLVED: To provide a jointed flexible image forming member belt having an improved seam form without a projection which hinders the movement of a subsystem of device. SOLUTION: This method for reducing the surface roughness of the welding seam of the image forming belt consists of a step 407 in which a belt part which contains the welding seam and a belt end part adjacent to the same is pressurized by a certain pressure, a step 409 in which the welding seam is heated up to the temperature to be heated which is near to the glass transition temperature, but is lower than the same while being pressurized, a step 411 in which the welding seam is, subsequently, cooled up to the temperature to be cooled, a step 413 in which whether the surface roughness is one to be satisfied or not is determined and a step in which the heating step 409, the cooling step 411 and the determining step 413 are repeated until the determining step determines that the surface roughness of the welding seam is the one to be satisfied. In such a manner, the surface roughness of welding seam of the image forming belt is reduced, the high spike-like projection is removed, a problem that a cleaning blade suffers a loss is removed, the efficiency of cleaning of blade is enhanced and an effective life is prolonged.

Abstract: PROBLEM TO BE SOLVED: To provide the method for prolonging the service life of a photoreceptor belt by decreasing the tension of the photoreceptor belt. SOLUTION: In a copying machine/printer, a system for prolonging the service life of the flexible photoreceptor belt 10 includes a tension applying roll 20 applying and decreasing the tension with respect to the belt 10. The tension of the photoreceptor belt is decreased at the finish of usual using, a week end, and a non-working day, so that the elongation of the size of the belt caused by creep is decreased, therefore, the charge carrying layer crack of the belt is restrained from being developed and the life time of the photoreceptor belt is prolonged about twice.
