Abstract
To provide an image forming apparatus in which the paper is cooled early by blowing air to the paper in the conveying path so as to prevent a sticking phenomenon on a paper output tray while paper turning, paper folding, paper breakage and paper jamming due to influence on paper conveyance by blowing air onto the paper in the conveying path, can be prevented. At the start of paper conveyance, a gate 73 is turned upwards to a first position to thereby close a sixth conveying path 44 and establish communication between a first conveying path 42 and a second conveying path 43 so that the paper having passed through a fixing unit 21 starts to be conveyed from first conveying path 42 to second conveying path 43. At the same time, air is exhausted from an exhausting mechanism 53 arranged upstream of a cooling mechanism 76. When a first paper sensor 74 detects the leading end of the paper, a cooling fan 77 starts to rotate at a predetermined rotational rate to start blowing air at a predetermined volume of cooling airflow.
