ABSTRACT:
An image forming apparatus has a first image forming unit for image reproduction from an original image and a second image forming unit for image reproduction from image signals for achieving easier interruption imaging and complicated image processing. Four modes are selectable, a normal mode, an analog mode, a digital mode and an overlay mode. An image forming apparatus is provided wherein an original image is converted into an electrostatic charge which is maintained. A first electrostatic latent image is formed on a recording medium according to the maintained charge. A second electrostatic latent image is formed on the recording medium according to an input image signal. In response to a demand for the second latent image, formation of the first latent image is interrupted and restarted after formation of the second latent image.
