An image forming apparatus includes a support frame, a cover, an electric component unit, a duct unit, and a fan. The support frame includes a second support portion disposed more rearward than a first support portion in a front-back direction of the image forming apparatus. The cover is more rearward than the second support portion in the front-back direction, and forms part of an image forming apparatus exterior. The electric component unit has a circuit board, and is between the second support portion and the cover in the front-back direction. The duct unit has an intake port located more frontward than the second support portion in the front-back direction, and is connected to the electric component unit. The fan is more rearward than the second support portion in the front-back direction, and takes in air from the intake port and discharge the air from an electric component unit exhaust port.
