トナー像を記録材に定着させる加熱ローラ定着装
置において、上記未定着トナー像に直接接触する
側の定着ローラに高出力熱源を有し、上記定着ロ
ーラに圧接する加圧ローラに低出力熱源を有し、
上記加圧ローラの熱源は両端部が高い発熱量の分
布を持つことを特徴とする加熱ローラ定着装置。 In a heating roller fixing device that fixes an unfixed toner image to a recording material by passing it between a pair of rollers, the fixing roller on the side that directly contacts the unfixed toner image has a high output heat source, and the fixing roller has a high output heat source. The pressure roller that comes into contact with pressure has a low output heat source,
A heating roller fixing device characterized in that the heat source of the pressure roller has a high calorific value distribution at both ends.
