Summary:PROBLEM TO BE SOLVED: To make it possible to control irregularity on an outer peripheral surface of a fixing belt to be a predetermined irregularity.SOLUTION: A fixing device comprises: an annular fixing belt that fixes an image formed on a recording medium to the recording medium while circulating to convey the recording medium; a reducing member that is in contact with an outer peripheral surface of the fixing belt to reduce the difference in irregularity on the outer peripheral surface; a forming member that is arranged on the inner peripheral side of the fixing belt and sandwiches the fixing belt with the reducing member to form a sandwiching part; and an adjustment mechanism that can adjust at least one of the angle of approach of the fixing belt into the sandwiching part and the angle of exit from the sandwiching part.SELECTED DRAWING: Figure 5 【課題】定着ベルトの外周面の凹凸を予め定められた凹凸に制御できるようにする。【解決手段】定着装置は、周回して記録媒体を搬送しながら、当該記録媒体に形成された画像を当該記録媒体に定着する環状の定着ベルトと、前記定着ベルトの外周面に接触して当該外周面の凹凸差を低減する低減部材と、前記定着ベルトの内周側に配置され、前記低減部材とで前記定着ベルトを挟んで挟み部を形成する形成部材と、前記定着ベルトの前記挟み部への進入角度及び前記定着ベルトの前記挟み部からの退出角度の少なくとも一方を調整可能な調整機構と、を備える。【選択図】図５
