    摘要： An image forming apparatus for forming hardcopy images by electrophotographic process using a developing device for toner developing and chargers for charging and discharging by corona discharge, the image forming apparatus having cleaners for removing toner adhering to a charge wire of each charger, each cleaner is operated when a predetermined amount of toner has been supplied to the developing device. In another example, each cleaner is operated when a toner accommodating bottle becomes empty and is detached from the image forming apparatus.

    摘要： An image forming apparatus wherein the copying operation is performed not only in an automatic density specifying mode but also in a manual density specifying mode according to select by an operator. When the ratio of the frequency of select of the manual density specifying mode to the frequency of select of the automatic density specifying mode has exceeded a predetermined value, the image forming apparatus is adapted to execute an image adjustment process by detecting the state of components, for example, charge wires for the purpose of adjusting the density of copy images formed in the automatic density specifying mode.

    摘要： A copying apparatus for forming a hard copy image through an electrophotographic process includes an image forming apparatus which can form an image on a recording paper in various density levels, and a diagnostic unit for discriminating the image forming apparatus into three states of being capable of forming a proper image, being operable but incapable of forming a proper image, and being incapable of operation. Since the image forming states of the copying apparatus are divided into three stages, appropriate operation is performed in the copying apparatus using the electrophotographic process in response to the state of the machine.

    摘要： An image forming apparatus which detects the cause of the image unevenness in the image formation of an electrostatic recording system used for a copying machine, laser beam printer or the like, and automatically takes measures responding thereto. This image forming apparatus includes a surface potential sensor for detecting charge unevenness after charging a photoconductive drum by a charger and a toner density sensor for detecting toner adhesion unevenness after developing by a developing unit, and based on the results of detections of these sensors, when charge unevenness exits, the apparatus judges that the cause of the image unevenness is an abnormal state of the charger, and cleans a charge wire, and when no charge unevenness exists and density unevenness exists, the apparatus judges that the developing unit is abnormal, and displays this abnormality and inhibits the operation of the apparatus. The apparatus further includes a toner sensor for detecting density unevenness after transfer, and when density unevenness is detected by this sensor, it is judged that the cause of the image unevenness is an abnormal state of a transferring charger, and displays this abnormality and inhibits the operation of the apparatus.
