Fixing heater control device
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 突入電流が少なく、温度制御上不具合のない 安定した定着性能を発揮する定着装置を提供する。 【解決手段】 発熱体を内蔵する加熱ローラと、該加熱 ローラに圧接される加圧ローラとを備え、これらローラ 間に、トナーが付着された記録紙を通過させ、該トナー を記録紙に定着させる。前記加熱ローラ1内の発熱体 は、突入電流の低いニクロム線ヒータH1と、それ以外 の突入電流が多く温度の立ちあがりのすばやいハロゲン ランプヒータH2とで構成されている。CPU4は、先 に突入電流の低いヒータH1から点灯し、次に突入電流 が多いヒータH2を点灯するような制御をする。 (57) [Abstract] [PROBLEMS] To provide a fixing device having a small inrush current and exhibiting stable fixing performance without trouble in temperature control. SOLUTION: A heating roller containing a heating element and a pressure roller pressed against the heating roller are provided, and a recording paper on which toner is adhered is passed between these rollers to fix the toner on the recording paper. Let The heating element in the heating roller 1 is composed of a nichrome wire heater H1 having a low inrush current, and a halogen lamp heater H2 having a large inrush current and having a rapid temperature rise. The CPU 4 performs control such that the heater H1 having a lower rush current is turned on first, and then the heater H2 having a higher rush current is turned on.
