PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of maintaining the separation efficiency between toner and air in a cyclone part at a suitable value.SOLUTION: There is provided an image forming apparatus which comprises: a first air duct 48; a toner collecting part 10 having a second air duct 15; and an air quantity adjusting part 90. The first air duct 48 guides toner-containing air. The toner collecting part 10 has a cyclone part 13, a collecting part 14, a second air duct 15 and a filter 16 provided in the second air duct. The cyclone part 13 communicates with the first air duct 48 and centrifugally separates toner from the toner-containing air. The collecting part 14 collects toner separated by the cyclone part 13 and the second air duct 15 guides air after toner is separated. The air quantity adjusting part 90 flows air into the first air duct 48 to adjust the air quantity of the toner-containing air passing through the first air duct 48. |
