シートの幅を設定するための設定手段と、シートにトナー像を形成する画像形成手段と、この画像形成手段により形成されたシート上のトナー像をニップ部にて加熱する加熱部材と、この加熱部材を送風により冷却する冷却手段と、この冷却手段による冷却領域をシートの設定幅に応じて変更すべく移動可能に設けられたシャッタと、を有する画像形成装置において、
シャッタとともに移動可能に設けられ加熱部材の冷却領域とこれよりも幅方向内側の非冷却領域の温度をそれぞれ検知する温度検知手段と、この温度検知手段による検知温度が上限設定温度に達するとシートの設定幅が誤りである旨を報知する報知手段と、を有することを特徴とする画像形成装置。 Setting means for setting the width of the sheet, image forming means for forming a toner image on the sheet, a heating member for heating the toner image on the sheet formed by the image forming means at the nip portion, and the heating In an image forming apparatus comprising: a cooling unit that cools a member by blowing air; and a shutter that is movably provided to change a cooling region by the cooling unit according to a set width of the sheet.
Temperature detection means for detecting the temperature each cooling region and the width direction inside the uncooled area than that of the heating member is movable together with the shutter, the sheet of the temperature detected by the temperature detecting means reaches the upper limit set temperature And an informing means for informing that the set width is an error. シートの幅を設定するための設定手段と、シートにトナー像を形成する画像形成手段と、この画像形成手段により形成されたシート上のトナー像をニップ部にて加熱する加熱部材と、この加熱部材を送風により冷却する冷却手段と、この冷却手段による冷却領域をシートの設定幅に応じて変更すべく移動可能に設けられたシャッタと、を有する画像形成装置において、
シャッタとともに移動可能に設けられ加熱部材の冷却領域とこれよりも幅方向内側の非冷却領域の温度をそれぞれ検知する温度検知手段と、前記温度検知手段により冷却領域の温度が下限設定温度に降下したことが検知されたとき、前記加熱部材の冷却領域を狭める方向に前記シャッタを移動させ、前記温度検知手段により非冷却領域の温度が上限設定温度に上昇したことが検知されたとき、前記加熱部材の冷却領域を広げる方向に前記シャッタを移動させることで加熱部材の冷却領域を補正する補正手段と、を有することを特徴とする画像形成装置。 Setting means for setting the width of the sheet, image forming means for forming a toner image on the sheet, a heating member for heating the toner image on the sheet formed by the image forming means at the nip portion, and the heating In an image forming apparatus comprising: a cooling unit that cools a member by blowing air; and a shutter that is movably provided to change a cooling region by the cooling unit according to a set width of the sheet.
Temperature detecting means that is provided so as to be movable together with the shutter and detects the temperature of the cooling area of the heating member and the non-cooling area on the inner side in the width direction . When it is detected that the temperature of the non-cooling region has risen to the upper limit set temperature, the heating member is moved in the direction of narrowing the cooling region of the heating member. image forming apparatus characterized by having a correction means for correcting the cooling region of the heating member in a direction to widen the cooling area to move the shutter. 冷却領域を補正するための前記シャッタの移動を段階的に繰り返し実行可能な構成としたことを特徴とする請求項２に記載の画像形成装置。 The image forming apparatus according to claim 2, wherein the movement of the shutter for correcting the cooling region can be repeatedly executed in a stepwise manner. 前記温度検知手段により冷却領域の温度が上限設定温度に上昇したことが検知されたとき、もしくは、前記温度検知手段により非冷却領域の温度が下限設定温度に降下したことが検知されたとき、シートの設定幅が誤りである旨を報知するための報知手段を有することを特徴とする請求項２または請求項３に記載の画像形成装置。 When the temperature detecting means detects that the temperature of the cooling region has risen to the upper limit set temperature, or when the temperature detecting means detects that the temperature of the non-cooling region has dropped to the lower limit set temperature, the image forming apparatus according to claim 2 or claim 3 in setting width and having a notification means for notifying an error.
