Abstract
An image-forming machine includes a photosensitive material drum, a developer mounted on a machine body so as to move in a direction to approach, and separate away from, the photosensitive material drum along guide means arranged in the machine body, and a protection cover that opens and closes a portion of the peripheral surface of the photosensitive material drum. The protection cover is supported by the machine body so as to rotate between a closed position and an opened position. An arm member is rotatably arranged in the machine body being drive-coupled to the protection cover so as to open and close the protection cover. An end of the arm member is so positioned as to be present on a locus of motion of the developer.
