ABSTRACT:
A door opening or closing detecting device and an image forming apparatus including a shaft member which is provided to a housing slidably along one end of a door, and urged to be brought into pressure contact with a pressing member through a pressure contact member, the shaft member being slid by the pressing member which moves with the opening/closing of the door. The opening/closing of the door is detected by a detecting portion according to sliding of the shaft member, and a power supply is interrupted by a switch portion. The door opening or closing detecting apparatus and the image forming apparatus are capable of reliably detecting the opening/closing of the door and appropriately interrupting the power supply while achieving space saving and reduction in size of the apparatus.
