摘要： An image forming apparatus is used in conjunction with a signal generator for producing an image signal representing an image to be recorded. The apparatus includes a device for forming a visible image with visible material on an image bearing member. The image is represented by the image signal produced by the signal generator. A time signal is also generated by a time signal generator and a measuring circuit measures the time signal so generated as a function of the production off the image signal by the image signal generator. Finally, a warning signal that indicates insufficiency of supply of the visible material for forming an image properly by the image forming device is produced on the basis of measurement of the time signal by the measuring circuit.
