Abstract
A device for developing an electrostatic latent image includes a developing housing having a developing chamber and stirrer chamber, a replenishing device for feeding the developing agent onto the peripheral surface of the developing roller, a stirring device disposed in the stirrer chamber to stir the developing chamber, and a developing agent detecting sensor disposed in the developing housing under the stirring device. The stirring device has a rotary shaft, a cleaning member mounted on the rotary shaft at a position corresponding to a development agent detector unit of the developing agent detecting sensor, and a stirrer member mounted on the rotary shaft at the side of the cleaning member. The stirrer member is provided with tilted guide portions for sending the stirred developing agent toward the developing agent detecting sensor.
