摘要:
A process cartridge detachably attached to an image forming apparatus includes a first subunit, a second subunit, a first positioning member, and a second positioning member. The first subunit accommodates a photoconductor therein. The second subunit accommodates a developer applicator therein. The photoconductor and the developer applicator are arranged substantially parallel to each other to define a development gap therebetween. The first positioning member is fastened to both the first and second subunits to position ends of the photoconductor and the developer applicator on a first side of the respective subunits. The second positioning member is fastened to only one of the first and second subunits to position ends of the photoconductor and the developer applicator on a second side of the respective subunits opposite to the first side. An image forming apparatus employing such a process cartridge is also disclosed.

摘要:
An image forming apparatus includes a unit, a mark detector, and a controller. The unit is attachable to and detachable from the image forming apparatus and includes an information mark pattern indicating predetermined information. The mark detector detects the information mark pattern. The controller obtains the information indicated by the information mark pattern based on a detection result provided by the mark detector.
摘要:
A system with a container including a protrusion, and a receiver to receive the container. The receiver includes a slide block that is movable relative to a body of the receiver, the slide block including two surfaces, a first surface, initially contacted by the protrusion of the container during insertion of the container into the receiver, having a first slope to resist movement of the container towards the receiver, and a second surface, subsequently contacted by the protrusion of the container during the insertion of the container into the receiver, having a second slope to interact with the protrusion of the container to assist movement of the container towards the receiver. This construction provides the user with a changing insertion force to indicate proper mounting of the container.
摘要:
A toner container for use with an image forming apparatus which includes a horizontally mounted toner body mounted within the image forming apparatus, a toner outlet to discharge toner in a downward direction, and a shutter to open and close the toner outlet which moves along a first and second rail. The second rail is disposed downstream of the first rail in the insertion direction of the toner body and parallel to the length of the toner body. The longitudinal length of the first rail is smaller than the longitudinal length of the second rail.

A toner container includes a cylindrical container body, a cap having a toner outlet, and a shutter. The cap includes a primary positioning primary positioning hole, formed in a top front surface perpendicular to a longitudinal direction of the toner container, extending in the longitudinal direction, to determine an installation position of the cap relative to the image forming apparatus, a secondary positioning hole, formed in a bottom front surface perpendicular to the longitudinal direction of the toner container, extending in the longitudinal direction forward the toner outlet, to subsidiary determine the installation position of the cap, and a first restriction member to position the cap in a horizontal direction perpendicular to the longitudinal direction, projecting vertically upward from an outer circumferential surface of the cap and symmetrical about a virtual perpendicular line passing through a cross-sectional center position of the primary positioning hole perpendicular to the longitudinal direction.
