Abstract
A safety mechanism for an open/close door member of an image forming apparatus includes a door member rotated around one axis to be opened and closed in a gravity force direction, a first lever member abutting against the door member in a closed condition, a second lever rotatably attached to an apparatus body and adapted to support the first lever member, and a biasing member for biasing the first and second lever members. When a load acting on the first lever member from the door member is greater than a set value, the lever member is shifted to a predetermined position to function as a stop device for stopping rotation of the door member, and, when the load is smaller than the set value, the rotation of the door member is permitted.
