An image forming apparatus includes an image memory section in an image processing section for temporarily storing an image signal read from an optical system via a photoelectric transducer section, an arithmetic section for numerical computation based on data stored in the image memory section, a decision section adapted to conclude that an image forming operation should be interrupted when a variation rate E of the image signal is lower than a threshold value T read from a ROM as a result of computation by the arithmetic section, and to conclude that the image forming operation should be continued when the variation rate E is equal to or higher than the threshold value T. A section is also provided for interrupting the image forming operation in response to a command from the decision section when there is no operator's key entry to order the interruption or execution of the image forming operation within a predetermined period of time.
