Abstract
A toner dispenser for a development system of an electrostatic processor has a removable reservoir which mates with a collar on a pivotally mounted hopper containing a dispensing roll. The reservoir may be slid into or out of the collar while upright, but after it is mounted the hopper is rotated to invert the reservoir so that there then is a gravitational flow of toner to the dispensing roll.
