Abstract
An image forming apparatus includes a body; a paper supply tray mounted in the body; a first sensor including a light emitting element and a light receiving element; a first actuator including a first actuating arm to sense the presence of the printing medium stored in the paper supply tray by coming into contact with and being moved by the printing medium, a second actuating arm to sense a width of the printing medium by selectively coming into contact with and being moved by the printing medium fed to the printing path according to the width of the printing medium, and a first sensing arm placed between the first actuating arm and the second actuating arm to intercept the light that would otherwise be transmitted to the light receiving element by being moved in linkage with the first actuating arm and the second actuating arm.
