Abstract
A toner container according to one example embodiment includes a housing having a reservoir for storing toner. A rotatable developer roll is mounted on the housing. A doctor blade has a distal end in contact with the outer surface of the developer roll along a length of the developer roll for metering toner on the outer surface of the developer roll. The doctor blade has a proximate end positioned against a portion of the housing. A toner agitator in the reservoir has a shaft. A support in the reservoir is positioned in close proximity to the shaft to limit bending of the shaft. A first end of the support contacts an inner surface of the portion of the housing that the proximate end of the doctor blade is positioned against. The support stiffens the portion of the housing that the proximate end of the doctor blade is positioned against.
