Abstract

A toner densification process for use in packaging of electrophotographic toners and related particulate products is disclosed. The process comprises releasing trapped air from the uppermost layers of toner particles in a freshly filled toner bottle on a toner pack line using ultrasonic vibratory agitation. Ultrasonic transducers located about the upper half of the toner bottle are energized as the bottle is being filled. The upper layers of toner particles liberate entrapped air that allows the toner to compact itself into about 10 to 30 percent less volume than an unagitated control toner bottle.
