Toner container

A toner cartridge according to one example includes first and second alignment guides that extend outward from a first side and a second side of the toner cartridge, respectively, for positioning the toner cartridge. The first and second alignment guides define a pivot axis about which the toner cartridge is pivotable relative to an imaging unit when the toner cartridge is installed on the imaging unit. An engagement member is positioned on a rear of the toner cartridge for receiving a bias force for biasing the toner cartridge about the pivot axis when the toner cartridge is installed on the imaging unit. The engagement member is positioned next to the bottom of the housing. The engagement member includes an angled contact surface that faces upward and rearward for contacting a corresponding hold-down on the imaging unit when the toner cartridge is installed on the imaging unit.

Toner cartridge having positioning features including guides extending outward from sides of the toner cartridge

A toner cartridge according to one example embodiment includes a reservoir for holding toner. An outlet is positioned on a front of the toner cartridge for exiting toner from the toner cartridge. First, second and third electrical contacts are positioned on a first side of the toner cartridge for contacting corresponding first, second and third electrical contacts in an image forming device. Each of the first, second and third electrical contacts of the toner cartridge is electrically connected to a respective imaging component positioned on the toner cartridge. The first, second and third electrical contacts of the toner cartridge are positioned such that an imaginary line that angles downward in a direction from a rear of the toner cartridge toward the front of the toner cartridge passes through the first, second and third electrical contacts of the toner cartridge.

Toner cartridge electrical contacts

A toner cartridge according to one embodiment includes a body having a reservoir for storing toner and a rotatable developer roll mounted on the body and in fluid communication with the reservoir. A portion of an outer surface of the developer roll is exposed along a front of the body for supplying toner from the reservoir to a corresponding photoconductive drum on an imaging unit when the toner cartridge is installed on the imaging unit in an operative position of the toner cartridge relative to the imaging unit. A first engagement member positioned on a rear of the body is configured to engage a corresponding second engagement member on the imaging unit when the toner cartridge is installed on the imaging unit to retain the toner cartridge in a storage position of the toner cartridge relative to the imaging unit with the developer roll spaced away from the photoconductive drum.

Replaceable units of an electrophotographic image forming device having a shipping or storage separator

A component separator system for use with an electrophotographic image forming device according to one example embodiment includes a first replaceable unit and a second replaceable unit for use in the image forming device. The second replaceable unit is manually separable from the first replaceable unit. The first replaceable unit is mateable with the second replaceable unit in an operative position of the first replaceable unit relative to the second replaceable unit with a first imaging component of the first replaceable unit in operative contact with a second imaging component of the second replaceable unit. Engagement of a first engagement member of the first replaceable unit with a second engagement member of the second replaceable unit retains the first replaceable unit in a storage position relative to the second replaceable unit with the first imaging component spaced away from the second imaging component.

Toner cartridge

A developer unit for an electrophotographic image forming device includes a developer roll rotatably mounted on a housing. The developer roll includes a shaft defining a rotational axis and a roll body cylindrically disposed around the shaft to form an outer circumferential surface of the developer roll. An end seal includes a curved rotary seal portion sandwiched between a pocket portion of the housing and the outer circumferential surface of the developer roll, such that an outer circumferential surface of the curved rotary seal portion contacts the pocket portion of the housing and an inner circumferential surface of the curved rotary seal portion contacts the outer circumferential surface of the developer roll. The pocket portion of the housing includes protrusions that contact the outer circumferential surface of the curved rotary seal portion to restrict movement of the end seal along an operative rotational direction of the developer roll.
