    • There is provided an image forming apparatus which effectively suppresses an increase in temperature of a heating means by an air blowing means when image formation is performed to a small-size recording material and can continuously perform the image formation even though the air blowing means.The image forming apparatus includes a heating means to heat a recording material to be conveyed, a cooling fan which blows air from an air blowing port facing a part of the heating means, a shutter which moves such that an opening width of the air blowing ports is regulated depending on a width of the recording material, and an error detecting means which detects an error of the cooling fan. When the error detecting means detects an error of the cooling fan, the shutter moves to such a position that the cooling fan in which an error is detected, so that image formation is continued.
    • 提供一种图像形成装置,当对小尺寸记录材料进行图像形成时,能够有效地抑制加热装置的加热温度的增加,并且即使通过吹风装置也可以连续地进行图像形成。 图像形成装置包括:加热装置,用于加热待传送的记录材料;一个冷却风扇,其从面对加热装置的一部分的空气吹送口吹出空气;活门,其使空气吹出口的开口宽度移动; 根据记录材料的宽度来调节;以及错误检测装置,其检测冷却风扇的误差。 当错误检测装置检测到冷却风扇的错误时,快门移动到这样一个位置,使得检测到错误的冷却风扇继续进行图像形成。
