| Zusammenfassung: | To provide an image forming device having a configuration in which cassette heaters 60A, 60B, and 60C and an environmental heater 61 are detachably mounted to the feeding units 28A, 28B, and 28C, and which is capable of suppressing excessive temperature rise near the developing units 8Y, 8M, 8C and 8K.SOLUTION: A CPU is configured to, when the heater is not attached to the feeding unit, cause a cooling fan 40 to execute a cooling operation when the environment sensor 39 detects that the temperature higher than the first temperature. The CPU is configured to, when the heater is attached to the feeding unit, cause the cooling fan 40 to execute a cooling operation when the detection result of the sensor 39 is equal to or higher than the second temperature which is lower than the first temperature.SELECTED DRAWING: Figure 1
【課題】給送部２８Ａ、２８Ｂ、２８Ｃにカセットヒータ６０Ａ、６０Ｂ、６０Ｃや環境ヒータ６１を着脱可能とした構成で、現像器８Ｙ、８Ｍ、８Ｃ、８Ｋ近傍の温度が上昇し過ぎることを抑制できる構成を提供する。【解決手段】ＣＰＵは、ヒータが給送部に装着されていない場合は環境センサ３９の検出結果が第１温度以上であることに応じて冷却ファン４０の冷却動作を実行する。一方、ヒータが給送部に装着されている場合は環境センサ３９の検出結果が第１温度よりも低い第２温度以上であることに応じて冷却ファン４０の冷却動作を実行する。【選択図】図１ |
