PROBLEM TO BE SOLVED: To optimize notification of maintenance time to a filter. A casing housing an image forming unit 5 for forming an image on a sheet P, a fan for discharging air inside the casing to the outside of the casing through an exhaust port communicating the inside and outside of the casing, and an exhaust port. A filter that is detachably attached, a filter counter 132 that counts the number of times an image is formed by the image forming unit 5, and whether maintenance is required for the filter based on the number of times the image is formed, the temperature inside the housing, and the temperature outside the housing.
