In an image forming apparatus having a suction type fan, a thermistor is disposed in a vicinity of the suction type fan and the outside air (outside air intake port), and the forced convection by the fan is utilized, whereby it is made possible to detect the outside air temperature with good accuracy (accurately and with good response) and obtain the information thereof. Also, in an image forming apparatus for effecting image recording on a recording sheet by the electrophotographic process, including a cooling fan, an outside air thermistor (temperature sensor) disposed in a vicinity of the cooling fan, and outside air temperature calculating device for calculating the outside air temperature on the basis of temperature information from the outside air thermistor, wherein the parameter of the electrophotographic process is changed on the basis of outside air temperature information from the outside air temperature calculating device, the outside air temperature calculating device finds an average value obtained by averaging temperatures detected by the outside air thermistor during the non-recording operation for a predetermined time, and judges a value obtained by subtracting a predetermined value from the average value as the outside air temperature.
