FIXIER- UND HEIZVORRICHTUNG FUER ELEKTROSTATISCHES KOPIERGERAET

摘要

A fixing and heating device for an electrostatic copying apparatus includes a fixing roller which (a) remains stationary at least until a toner is softened, (b) is driven at a low speed to even the surface temperature of the fixing roller when the surface temperature is lower than a temperature suitable for fixing and when the surface temperature is equal to the temperature suitable for fixing except during a fixng operation, and (c) is driven at a speed suitable for fixing when the surface temperature is suitable for fixing during the fixing operation.
