Abstract
An image forming apparatus employs a device that detects the opening and closing of covers. Two covers are pivotally mounted to a body of the image forming apparatus, each of the two covers being movable either to its opening position to open with respect to the image forming apparatus or to its closing position to close with respect to the image forming apparatus. A movable member is positioned at a first position when both the two covers are at their opening positions. A micro switch detects whether the two covers are closed or opened with respect to the image forming apparatus. When one of the two covers has moved to its closing position causing the movable member to move to a second position and the other of the two covers is at its closing position, the detector detects that the two covers are closed.
