Abstract

A control portion of an image forming apparatus causes an operation of a first fan start and then causes a second fan to start. The time when the operation of the second fan starts is from a predetermined time before the time when the leading end of one sheet reaches a fixing nip to the time when the rear end of the one sheet passes through the fixing nip. In this way, since the second fan operates after the first fan operates, fine particle dust is hardly discharged to the outside of the image forming apparatus, and it is possible to suppress dew condensation inside the image forming apparatus.
