1. An image forming apparatus for forming an image on a recording material, the image forming apparatus comprising:
a plurality of cartridges each including a developing member for developing an electrostatic latent image formed on a photosensitive member with toner;
a fixing device configured to fix an unfixed toner carried on the recording material;
a fan configured to supply air; and
a duct configured to guide the air supplied from the fan to a predetermined cartridge closest to the fixing device of the plurality of cartridges,
wherein the predetermined cartridge includes a top surface positioned above in a vertical direction, of two surfaces which the predetermined cartridge includes and which cross in the vertical direction,
wherein, at one end side of the predetermined cartridge in a rotational axis direction of the photosensitive member, the duct includes a first part for discharging the air supplied from the fan in a first direction toward downward from upward in the vertical direction to the top surface, and a second part for discharging the air supplied from the fan, above the top surface in the vertical direction, in a second direction along the rotational axis direction of the photosensitive member, and
wherein the air discharged from the first part and the air discharged from the second part collide with each other above the top surface.
