Abstract
Abstract A process unit includes a unit frame having a pair of walls arranged in a width direction to maintain a distance and a developing device mounted between the pair of side walls of the unit frame. The developing device has a toner container that includes a container body having an opening formed in the bottom surface thereof and a sealing member that is peelably stuck to the bottom surface of the container body to close the opening. The sealing member has one end to which is coupled a grip member that can be pulled to remove the sealing member from the bottom surface of the container body to open the container opening. An anchor means is disposed on a wall on one side of the container body, so that the grip member is detachably anchored thereto without outwardly protruding in the width direction. The grip member extends along the wall of the container body. An opening and a mounting device are disposed at a wall on one side of the unit frame and are juxtaposed with respect to each other. The grip member is detachably mounted on the mounting device so as to partly protrude outwardly through the opening in the unit frame wall.
