IPC: G03G15/20
Filed: 1988-12-15
Abstract: PURPOSE:To reduce power consumption by preheating a heating body to a temperature below a fixing treatment temperature before recording material is carried to the heating part. CONSTITUTION:The heating body 21 is an oblong linear heating body of low thermal capacity, where the intersecting direction of a fixing film (the direction perpendicular to the traveling direction of the fixing film 24) is longitudinal. A heat generating layer 28 receives pulse energization via electrodes 50 and 50, is energized and heated in the form of a pulse.
