A process unit includes a photosensitive member that carries an image; a developing device that has a developer carrying member carrying a developer to be supplied to the photosensitive member; a rotating shaft that supports the developing device rotatably for approaching and separating from the photosensitive member; a photosensitive member gear provided to the photosensitive member; and a developing gear provided to the developer carrying member. The photosensitive member gear and the developing gear engage together and driving force can be transmitted, and the rotating shaft is placed on a driving force vector between the gears or on an extended line thereof, the driving force vector being generated from engagement between the photosensitive member gear and the developing gear.

A developer container includes: a container body that stores a developer and includes a filling port for the developer; and a container terminal that is attachable to and detachable from the container body. The container body is provided with an identifier that engages with the container terminal and is caused to change own form that can be identified from an outside, by an external force that is applied to detach the container terminal from the container body. The container body is provided with a flow preparation part that separates an inside and outside of the container body before changing the form of the identifier and that allows the air to flow between the inside and outside of the container body after changing the form of the identifier.

A development device includes a development housing, a first developer conveyance member, a developer bearer, and a developer amount detector to detect an amount of developer in the development housing. The developer amount detector includes a light-emitting element, a right-receiving element, a first light guide including a first end from which light enters and a second end disposed inside the development housing, and a second light guide including a first end positioned inside the development housing across a predetermined distance from the second end of the first light guide and a second end from which the light exits. The second end of the first light guide and the first end of the second light guide are arranged in an axial direction of the first developer conveyance member with a light transmission path therebetween partly inside a locus of rotation of the first developer conveyance member.

The developer container includes a rotator that is rotated in the container body, a sequence of gears disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion that fits with a main body side guiding portion and guides the developer container in a direction in which the developer container is attached to a mounting portion of an image forming device main body. A first gear included in the sequence of the gears is movable between an operating position where the first gear engages with a second gear and a retracted position where the first gear is retracted. On a surface on which the container guiding portion is disposed, a part of the container guiding portion is disposed within a projected area of the first gear being disposed at the operating position.

A charger adapted to uniformly charge a surface of an image bearing member is provided. The charger includes a charging roller, a charging roller cleaning member, and a cleaning member moving device. The charging roller is in contact with a surface of the image bearing member and is rotatable. The charging roller cleaning member is in uniform contact with the charging roller in a longitudinal direction. The cleaning member moving device is adapted to reciprocate the charging roller cleaning member in a direction orthogonal to the longitudinal direction of the charging roller while keeping the charging roller cleaning member in contact with the charging roller.

摘要:
An image forming apparatus comprises a exposure device as a light source, a developer container storing developer and attached to a main body of the image forming apparatus perpendicular to a lengthwise direction of the photoconductor, a developing unit and a photoconductor unit having a photoconductor for bearing a latent image thereon each detachably attached to the main body substantially in the same direction as the developer container. An exposure device displacing mechanism displaces the exposure device between a first position enabling the exposure device to function as the light source and a second position disabling the exposure device to function as the light source. The photoconductor unit is detached when the developer container is either displaced from an initially attached position or is removed from the main body and the exposure device displacing device has displaced the exposure device to the second position.
