Claims

[Claims for Utility Model Registration] A fixing roller with a built-in heater, a pressure roller that comes into pressure contact with the fixing roller, a separating claw that separates the transfer paper from the fixing roller, and a paper discharge roller that separates the transfer paper separated by the separating claw. In a heating fixing device having upper and lower paper ejection guides that lead to the upper and lower paper ejection guides, the base is fixed to the lower paper ejection guide on the side opposite to the paper ejection roller, and is gradually separated upwardly so as to be connected to the nip portion of the fixing and pressure rollers. A heat fixing device comprising an auxiliary guide made of an elastic piece that is lifted upward from a line connecting the nip portions of the pair of paper discharge rollers, reversed near the fixing roller, and returned to the lower paper discharge guide. .
