IMAGE FORMING APPARATUS

摘要

An image forming apparatus is provided to block heat from a fusing unit by a heat blocking member and minimize a heat increase of a cover because outside air circulating chamber and the heat blocking member are cooled while outside air circulates toward the outside air circulating chamber by natural air current wherein the outside air circulating chamber is between the cover and the heat blocking member. A fusing unit(40) is installed in a body(1). A cover(60) is installed in a body to open a side which faces the fusing unit. A heat blocking unit(70) is installed in the inside of the cover to block heat from the fusing unit. An outside air circulating chamber(80) is between the heat blocking member and the cover. Outside air circulates by convention current in the outside air circulating chamber. At least one outside air flowing hole(64) flows air in the outside air circulating chamber.
