QUICK HEAT ROLLER FOR HEAT ACCUMULATION TYPE FIXING

摘要

PROBLEM TO BE SOLVED: To realize a heat roller for heat accumulation type fixing whose service life is long, which can be heated at a very high speed and which can respond to processing speed at a high speed when it is systemized with another OA equipment in an electrophotographic device such as a copying machine and a printer. ;SOLUTION: A heating resistor sheet is manufactured by forming a film by laminating an insulating layer 6,a heating resistor layer 8, an insulating layer 14 and the like on a metallic sheet 4 whose surface is roughened and which is composed of aluminum, copper, stainless steal or the like by a screen printing method. Then, the quick heat roller for heat accumulation type fixing is completed by winding the heating resistor sheet round the outside circumference of a metallic pipe stock 16 having a heat insulating layer 18 at the surface and sticking it so that the sheet 4 becomes the outermost outside circumference. At this time, the layers 14 and 18 are brought into close contact with each other and joined.;COPYRIGHT: (C)2000,JPO
