Abstract
An apparatus in which the distribution of tones particles is measured as a function of the size and charge thereof. The toner particles pass through a uniform electrical field in the interior chamber of the housing. The resultant deflection from a reference is a function of the size and charge of the particle. A computer driven image analysis system displays a toner charge distribution.
