To provide a safety system and a sub-unit for image forming device, of which the reliability is improved without using any mechanical switch and an image forming device.
In this safety system, a sub-unit 3 itself is constituted as a switch component 6 so that in the state of mounting the sub-unit 5 on a unit holding part 2, a regulation object 4 for safety and a power supply source 5 can be connected and in the state of detaching the sub-unit 3 from the unit holding part 2, the regulation object 4 for safety and the power supply source 5 can be disconnected. Besides, the image forming device, in which this safety system is used as a first safety system 11 and further a second safety system 12 provided with a confirming means 13 for confirming the state of mounting the sub-unit 3 to the unit holding part 2 is added inside the sub-unit 3, is also provided as an object. Moreover, the sub-unit 3 constituting each of the safety systems 11 and 12 is also provided as an object.
