FIXING DEVICE FOR ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fixing device for an electrophotographic device capable of shortening a warm-up time while preventing power consumption by preheating to the utmost by overcoming the weak point of an aluminum alloy having low creep strength while adopting the aluminum alloy advantageous in terms of heat conductivity and workability. SOLUTION: In this fixing device for an electrophotographic device which is equipped with a pressure roller 12 and a fixing roller 11 and where toner 23 is heated and melted in the case of making recording paper 24 where a toner image is formed pass between the rollers 11 and 12 and the toner image is fixed by pressuring the toner 23; an Mn-aluminum alloy is used as the material of the core bar of the roller 11.
