Abstract: A sealing assembly according to one example embodiment includes a housing and an imaging component positioned on the housing. A seal has opposed first and second edges extending along a longitudinal dimension of the seal. A lateral dimension of the seal is perpendicular to the longitudinal dimension and extends in a direction from the first edge to the second edge.

Abstract: A toner cartridge according to one example embodiment includes a housing having a reservoir for containing toner therein. An exit port in fluid communication with the reservoir faces downward on a front of the housing near a first side of the housing. A portion of a main interface gear for providing rotational power to a toner delivery system is exposed on the front of the housing near a top of a second side of the housing and engagable with a corresponding drive gear in the image forming device. A projection projects from the front of the housing and is spaced from the exit port toward the first side of the housing. The projection extends further forward than a frontmost portion of the exit port. A front of the projection is unobstructed for engaging a shutter on a developer unit when the toner cartridge is inserted into the image forming device.
