ABSTRACT:
An image forming apparatus includes a plurality of devices for forming an image on a rotatable medium and transferring the image onto transfer material. A detector is provided to detect the electrical condition of one of the devices during an initial turn of the rotatable medium prior to image processing. Electrical circuitry then controls the electrical condition of the one device to approach a predetermined value which value is then held for controlling the device during image formation.
