PROBLEM TO BE SOLVED: To provide a controller for electric products which incorporates an electric product composed of electromagnetic conversion means and an electric product composed of a photoelectric conversion means and is suitable for the safety improvement of the electric products and a control system, and an image forming device incorporating the controller. SOLUTION: This controller is provided with a parallel circuit obtained by connecting in parallel a plurality of serial circuits obtained by serially connecting the electric products consisting of electromagnetic conversion means SOL1, SOL2, and CL1 and photoelectric conversion means (light source 13) and transistors Q1 to Q4 switching current caused to flow to the electric products, repeats reset operation of the electric products as many as the prescribed number of times in case a detecting part 12 detects the voltage abnormality of the electric products, and interrupts voltage applied to the electric products by a protective circuit (transistor Q5 and Q6) in case voltage abnormality is further detected. |
