ABSTRACT:
An image forming apparatus includes a movable image bearing member; an image forming device for forming a toner image on the image bearing member; a charging member for charging the image bearing member in a charging station; and an electrical power source for supplying power to the charging member. A detector detects the voltage-current characteristic between the charging member and the image bearing member; and a controller controls the output of the electrical power source, in accordance with an output of the detector, when a surface area portion of the image bearing member, where the toner image is not going to be formed as the image bearing member rotates, is in the charging station.
