Image forming apparatus and developer container, developing device, process unit, and replaceable unit therefor

摘要

An image forming apparatus includes an apparatus body, an apparatus-side terminal provided to a first inner side wall of the apparatus body, a developer container to contain developer and to be removably installable in the apparatus body, a container-side terminal electrically connectable to the apparatus-side terminal and disposed in a first end portion of the developer container in a longitudinal direction thereof, and an apparatus-side protrusion projecting inward from the first inner side wall of the apparatus body. In removal of the developer container from the apparatus body, a second end portion of the developer container in the longitudinal direction is disengaged from the apparatus body before the first end portion is disengaged from the apparatus body, and the apparatus-side protrusion contacts the first end portion of the developer container immediately after removal of the developer container from the apparatus body is started.

主权项

1. An image forming apparatus comprising:
an apparatus body including an apparatus-side terminal provided to a first inner side wall of the apparatus body; a developer container to contain developer, removably installable in the apparatus body, the developer container including a container-side terminal disposed in a first end portion of the developer container in a longitudinal direction thereof, the container-side terminal electrically connectable to the apparatus-side terminal; an apparatus-side protrusion that projects inward from the first inner side wall below an upper portion of the first inner side wall and above a lower portion of the first inner side wall of the apparatus body to contact the first end portion of the developer container immediately after removal of the developer container from the apparatus body is started; and an additional apparatus-side protrusion that projects inward from the first inner side wall of the apparatus body and is positioned across the apparatus-side terminal from the apparatus-side protrusion, wherein, in removal of the developer container from the apparatus body, a second end portion of the developer container in the longitudinal direction is disengaged from the apparatus body before the first end portion is disengaged from the apparatus body.
