Abstract
In a development unit for electrostatographic printing, where toner particles are conveyed by a rotating roll to a charge-retentive surface, a groove is defined in the interior surface of the housing which retains the toner particles, the groove extending along a portion of the circumference of the roll. The groove facilitates redistribution of toner particles which accumulate at the bottom of the housing near an end of the roll.
