ABSTRACT:
A device for developing an electrostatic latent image including a developing housing having a developing chamber, a stirrer chamber, and a developing agent-feeding port communicating with the stirrer chamber. A developing roller is disposed in the developing chamber to hold, on the peripheral surface thereof, a developing agent in a developing agent-holding zone, and convey the thus held developing agent to a developing zone to apply it to the electrostatic latent image. A replenishing device feeds the developing agent onto the peripheral surface of the developing roller in the developing agent-holding zone. A stirring device disposed in the stirrer chamber stirs the developing agent that is fed through the developing agent-feeding port and sends the stirred developing agent to the developing chamber. A vibration plate having a plurality of developing agent-flow ports is disposed at the developing agent-feeding port of the developing housing, and the stirring device is caused to act on the vibration plate.
