  • Publication number: 20200249592
    Abstract: A developer container includes a body and a shutter member. The body has an opening and a containing part. The containing part is to contain a developer put into the containing part through the opening. The shutter member includes a tip portion in a first direction. The shutter member is slidable between a closing position at which the shutter member closes the opening and an open position at which the shutter member leaves the opening open. The shutter member slides in the first direction and thereby moves from the open position to the closing position. The tip portion includes a top surface and a pair of side surfaces. The top surface has inclination that causes a distance in a third direction from the opening to the top surface to decrease in a second direction. Spacing in a fourth direction between the side surfaces is narrowed in the second direction.
