摘要：Within a fixing roller () are disposed a main heater lamp () for heating a centralportion of the fixing roller and a sub-heater lamp () for heating opposite end portions ofthe fixing roller. MRnh, SRnh and ΣRnh satisfy the formula (1) or (2): Σ≧30.5·()+382
formula (1) ≦−21.9·()−198 formula (2), where MRnh is a mean value of heat distributionin a no-heat generating section of the main heater lamp; SRnh is a mean value of heatdistribution in the a no-heat generating section of the sub-heater lamp; ΣRnh is the sumtotal of these mean values; and Ht=vp/(Mh·λ) where vp is a fixing speed (m/s), Mh a heatcapacity per unit length of the heating member (J/(° C.·m)) and λ a heat conductivity of amaterial forming the heating member (W/(m·° C.)).
