PROBLEM TO BE SOLVED: To prevent a circuit of a post stage from being affected, even if a delay amount by a delay circuit inside an operation circuit varies dynamically, because of power supply voltage shift or temperature fluctuation, or the like, in an electronic device including an image forming apparatus.SOLUTION: The electronic device includes the operation circuit 8 including the delay circuit; a delay speed measuring circuit 9 for measuring the first signal advancing speed of a prescribed delay circuit when starting signal delay by the delay circuit and the second signal advancing speed of the prescribed delay circuit at certain timing, after starting the signal delay by the delay circuit inside the operation circuit 8; and a correction circuit 10 for correcting an operation result by the operation circuit 8, on the basis of the first signal advancing speed and the second signal advancing speed measured by the delay speed measuring circuit 9. |
