摘要： Provided is an image forming apparatus including a toner, and a fixing device configured to fix an image formed with the toner on a recording medium. The fixing device includes a fixing belt that is an endless belt, and a planar member configured to heat the fixing belt. An environmental fluctuation rate X is 45% or greater but 85% or less, and the environmental fluctuation rate X is represented by: Environmental fluctuation rate X = (Q1－Q2)/{(Q1＋Q2)/2} where Q1 is a quantity of electric charge of the toner in an environment having a temperature of 10 degrees Celsius and relative humidity of 15%, Q2 is a quantity of electric charge of the toner in an environment having a temperature of 27 degrees Celsius and relative humidity of 80%, and a unit for Q1 and Q2 is μC/g.

摘要： A fixation device includes a fixation member including a heating member, a pressure-application member press-contacting the fixation member forming a nip portion, an exciting coil induction-heating the heating member, a first temperature detection unit detecting a first temperature of the pressure-application member or a first ambient temperature of the fixation member, a second temperature detection unit detecting a second temperature of the fixation member, and a control unit selecting a temperature control mode or power control mode controlling power to the exciting coil. When the first temperature exceeds a first threshold temperature or the first ambient temperature exceeds a first ambient threshold temperature, the control unit selects the temperature control mode, and while the first temperature is equal to or lower than the first threshold temperature or the first ambient temperature is equal to or lower than the first ambient threshold temperature, the control unit selects the power control mode.
摘要翻译：固定装置包括：固定构件，其包括加热构件，压力接触形成夹持部的固定构件的加压构件，感应加热构件的励磁线圈;检测压力的第一温度的第一温度检测单元所述固定构件的第一环境温度，检测所述固定构件的第二温度的第二温度检测单元以及控制所述激励线圈的功率的温度控制模式或功率控制模式的控制单元。当第一温度超过第一阈值温度或第一环境温度超过第一环境温度时，控制单元选择温度控制模式，并且当第一温度等于或低于第一阈值温度或第一环境温度等于或低于第一环境阈值温度时，控制单元选择功率控制模式。
