Abstract

A toner concentration sensor is located adjacent a transport auger within the developer sump. The toner concentration sensor projects from the bottom wall of the developer sump towards the transport auger to an extent that the sensor overlaps with the blade of the auger. A portion of the auger blade is notched to avoid contact between the auger blade and toner concentration sensor. The position of the sensor allows for accurate toner concentration sensing due to the active flow of toner material across the surface of the sensor.
