Abstract:
A developing device, includes a first storage chamber that stores developer; a first conveyor that is disposed in the first storage chamber and conveys developer; a developer supporter that is disposed so as to face an image supporter, supports developer conveyed from the first conveyor, and conveys the supported developer to a developing position where an electrostatic latent image formed on the image supporter is developed; a second storage chamber that stores developer conveyed via the developing position and communicates with the first storage chamber at a confluent opening; a second conveyor that is disposed in the second storage chamber and conveys developer conveyed via the developing position toward the confluent opening; and a third storage chamber that stores developer overflowing in a case where an amount of developer in the second storage chamber becomes a predetermined amount or more.

Claim (Index 13):
An image forming apparatus, comprising:\n an image supporter; a writer to form a latent image on the image supporter; the developing device described in  claim 4  that develops a latent image on the image supporter.\n a detection sensor that detects whether a predetermined amount or more of developer is stored in the third storage chamber; \n an opening and closing member that opens and closes the communication path; and \n a processor that controls opening and closing actions of the opening and closing member in response to an output of the detection sensor, \n wherein the processor opens the communication path in a case where the developer is stored in the third storage chamber, and closes the communication path in a case where the developer is not stored in the third storage chamber.
