Fixing device, image forming apparatus, and method for controlling fixing device, each of which is for setting temperature of fixing member and temperature of external heating section for heating fixing member in order to carry out fixing process with respect to recording material for which set fixing temperature needs to be set higher than warm-up completion temperature by predetermined temperature or more
Abstract:
In a case where a process is carried out with respect to an envelope in a fixing process mode, at least either (i) a set temperature of a fixing roller in a fixing process or (ii) a set temperature of an endless belt in the fixing process which endless belt is provided in an external heating device is changed in accordance with a time period between an end of a warm-up mode and a start of the fixing process mode. This makes it possible to prevent both a wrinkle and inadequate fixing in a fixing process of an envelope carried out by a fixing device of an external heating method.
Abstract(Chinese):

在以定影处理模式进行相对于封套的处理的情况下，至少在（i）定影处理中的定影辊的设定温度或（ii）定影辊的定影温度 根据预热模式的结束和定影处理模式的开始之间的时间间隔来改变在外部加热装置中设置环形带的定影处理。 这使得可以防止由外部加热方法的定影装置进行的信封的定影过程中的褶皱和不充分的固定。
