Abstract
An automatic cleaning method for cleaning an electrifier of an image forming apparatus. A drive mechanism moves the cleaning member to clean the electrifier. An electrification time measuring section measures an electrification time of the electrifier after the last cleaning of the electrifier. A medium detecting section discriminates whether or not a medium is located in an image forming station. A control section controls the drive mechanism to render the cleaning member to clean the electrifier when a medium is not present in the image forming station after the measured electrification time reaches a determined time. The result is that automatic electrifier cleaning can be done at an appropriate preset timing, causing an elongated service life of the electrifier.
