摘要： A fixing device includes: a fixing roll that is rotatable; a belt member that is stretched over the fixing roll; a pressurizing roll that pressurizes the fixing roll via the belt member; a belt pressing member that presses an outer surface of the belt member to the pressurizing roll from inside of the belt member on a downstream side at a pressure-contact position between the fixing roll and the pressurizing roll; and a controller that decrease a time difference between a passage time per unit area of a tip region of a recording medium and a passage time per unit area of a succeeding region of the recording medium to pass a pressure-contact portion between the fixing roll and belt pressing member and the pressurizing roll.

摘要： A fixing device includes an endless belt, a fixing rotating body that contacts with and separates from the belt and fixes an image formed on a recording medium nipped between the fixing rotating body and the belt while rotating in contact with the belt, a support member provided so that the belt slides on the support member during circulation, the support member supporting a load provided when the fixing rotating body is in contact with the belt so as to form a nip portion where the recording medium is nipped between the belt and the fixing rotating body, a guide member that guides the recording medium to separate the recording medium from the belt after the recording medium passes through the nip portion, and a moving unit that moves the guide member away from the belt along with separation of the fixing rotating body from the belt.
摘要翻译：固定装置包括环形带，固定旋转体，其与皮带接触并与皮带分离，并固定形成在夹持在固定旋转体和皮带之间的记录介质上的图像，同时与皮带接触转动;支撑部件，使得所述带在循环期间在所述支撑构件上滑动，所述支撑构件支撑当所述固定旋转体与所述带接触时提供的负载，以便形成所述记录介质夹在所述带和所述固定旋转之间的夹持部引导构件，其在记录介质通过夹持部分之后引导记录介质将记录介质与带分离;以及移动单元，其使得引导构件沿着固定旋转体的分离而远离带移动，皮带。
