An image forming apparatus equipped with a sensor for detecting the requirement of replenishment and exchange of expendable supplies, parts and the like and an image forming structure capable of forming on the same sheet of paper a prewarning image in addition to a regular image formed corresponding to an original or image information to be copied. The image forming structure receives different control depending on whether or not the sensor is detecting the requirement of replenishment and exchange, wherein if the sensor is not detecting the requirement, it forms only a regular image while when the sensor detects the requirement, it forms a prewarning image together with a regular image thereby indicating the requirement of replenishment and exchange by the prewarning image on the same sheet on which a regular image is formed.
