Abstract

PURPOSE: To obtain fixed images of sufficient image densities without increasing the image densities before fixing by providing a heating member which radiates radiant heat to an image base behind the flash lamp provided in opposition to the moving path of the image base.
CONSTITUTION: A detector 17 which detects the leading end of transfer paper is provided before a flash fixing device 16 and a flash lamp 14 is lighted upon detecting the leading end of transfer paper or after lapse of a specified time. The transfer paper having been fixed by the flash fixing device 16 is conveyed to a heating roller fixing device 18. The heating roller device 18 is provided with a fixing roller 19 and a pressing roller 20 respectively above and below with the transfer paper path in-between and heating heaters 21, 22 are provided in both rollers. Thereby, fixed images of sufficient image densities may be obtained without particularly increasing the toner image densities before fixing.
