Abstract: The present disclosure relates to a polyester chemically produced toner composition including a core shell toner particle having special surface features and method to make the same. The special surface features on the outer surface of the core shell toner particle are created by the incorporation of a specially designed latex having styrene and acrylate monomers into the core of the toner particle wherein the latex in the core is tailored to be incompatible with the polyester resin(s) found in the core of the toner particle. The final ratio of the monomers in the latex to the surfactant in the latex is approximately 1:5. This ratio is key in maintaining a stable dispersion and is influenced by the particle size in the dispersion and surfactant chemistries.

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.
