Abstract:
An image forming apparatus includes a fixing part that fixes an unfixed toner image transferred to a sheet of paper by a fixing member being heated, a duct having an inner opening facing the fixing member and an outer opening spaced apart from the fixing member, a fan capable of changing a flow direction of air inside the duct, a filter that collects particulates flowing inside the duct, and a hardware processor that controls the fan to rotate in a direction to draw air into the duct from the inner opening to collect the particulates from a vicinity of the fixing member, and that, at a timing at which to cool the fixing member, controls the fan to rotate in a direction to blow air inside the duct toward the fixing member from the inner opening.

Claim (Index 3):
The image forming apparatus according to  claim 1 , wherein the duct includes:\n a plurality of inner air flow paths extending between the inner opening and the fan and respectively facing axial end portions and an axial center portion of the fixing member at the inner opening; and an inner valve mounted on at least one of the plurality of inner air flow paths and capable of opening and closing the at least one of the plurality of inner air flow paths, wherein the inner valve is opened and closed to switch between blowing the air toward the axial end portions of the fixing member and blowing the air toward a whole axial area of the fixing member.
