A developing device includes: a container that contains developer; a developer holder that rotates with the developer being held on a surface thereof to transport the developer to a developing region; and a cooling unit. An introduction port is provided at a position corresponding to the developing region, the introduction port allowing suction of a floating substance generated in the developing region in a transverse direction of the container. The cooling unit is connected to the introduction port to allow passage of gas containing the floating substance in a longitudinal direction of the container, and cools the container with the gas. An intake port is connected to an end of the cooling unit in the longitudinal direction, the intake port allowing introduction of gas.
