FIXING ROLL, FIXING DEVICE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve usability and saving of energy by speeding up the starting time for a fixing device. SOLUTION: In a halogen heater 23 provided inside a fixing roll 18, a glass tube 28 is formed from transparent quartz and its thickness is made to be <=8 mm and the transmissivity is improved. Thus, the heat loss due to the gloss tube 28 at the starting time of the fixing device is reduced.
