Abstract
An image forming apparatus includes a developing device including a developing roller to bear a developing agent to develop a latent image formed on an image bearing member, a cooling device to reduce an internal temperature of the image forming apparatus, a controller to calculate a travel distance of the developing roller to control the cooling device, and a memory unit to store the total travel distance of the developing roller. The controller calculates the total travel distance of the developing roller every Y minutes in the last X minutes, and a difference between the latest total travel distance of the developing roller and the total travel distance stored Z minutes ago by the memory unit to obtain the total travel distance during Z minutes and operate the cooling device for W minutes after image forming operation where the difference is equal to or greater than a threshold value M.
