Cooling device and image forming apparatus

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 the 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.

Description

technical field [0001] The present invention relates to a cooling device and an image forming device. Background technique [0002] Conventionally, image forming apparatuses such as printers and copying machines have been widely used. In most image forming apparatuses, a fan for cooling the inside of the image forming apparatus is provided to avoid increasing the internal temperature of the image forming apparatus, and the fan cools the inside of the image forming apparatus during image formation (for example, see Japanese Patent No. 2610119). In general, the cooling efficiency of the fan (for example, the rotation speed of the fan) is maintained at the same level when the output conditions specified by the user (such as the number of output sheets or single-sided or double-sided output) are not changed. [0003] However, even if the output conditions specified by the user are constant, the internal temperature of the image forming apparatus may tend to increase depending o...
