Title: Heating device
Inventor: HASEGAWA KAZUHIRO
IPC: G03G15/20
Filed: 2003-02-04
Abstract: <P>PROBLEM TO BE SOLVED: To improve temperature control accuracy and image quality.  <P>SOLUTION: In the heating device, the fixing roller 51 is heated by a heater 54 incorporated in it and an external heat roller 53. The external heat roller 53 can be brought into contact with the fixing roller 51 and separated from it. When sheet conveyance is stopped for a fixed interval or longer after consecutive conveyance of sheets, the heating device separates the external heat roller 53 from the fixing roller 51. This prevents such a condition that only the temperature of the surface of the fixing roller 51 is high and the temperature of the inside of the fixing roller 51 is low.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
