Abstract
A cooling device that cools the inside of an image forming apparatus provided with a developer carrier that carries an image developed with a developer while being rotated. The cooling device includes: a counting unit that counts an accumulative number of rotation of the developer carrier; and a fan that cools the inside of the image forming apparatus. The cooling device further includes: a calculating unit that calculates an abrasion amount of the developer carrier in which the accumulative number of rotation counted by the counting unit is used as at least one variable; and a controlling unit that actuates the fan with cooling efficiency according to the abrasion amount calculated by the calculating unit.
