Abstract
An image forming apparatus, a developing agent container and a controlling method of the same that improves a supply rate of developing agent from a developing agent container to a developing device that provides the developing agent to an image carrier.
Claims27
An image forming apparatus comprising:
- a developing device to provide a developing agent to an image carrier;
- a developing agent container to store the developing agent and comprises a supply unit to provide the stored developing agent to the developing device;
- a detecting member to detect a remaining amount of the developing agent in the developing agent container;
- and
- a controller to change a driving rate of the supply unit when the remaining amount of the developing agent detected by the detecting member is less than a predetermined level.
A controlling method of a supply unit of a developing agent container, the method being applied to an image forming apparatus comprising a developing device to provide a developing agent to an image carrier, and the developing agent container storing the developing agent and comprising the supply unit to provide the developing agent to the developing device, the method comprising:
- detecting a remaining amount of the developing agent in the developing agent container;
- and
- changing a driving rate of the supply unit when the remaining amount of the developing agent detected by a detecting member is less than a predetermined level.
A controlling method of an image forming apparatus which comprises a developing device to provide a developing agent to an image carrier, and a developing agent container which stores the developing agent and comprises a supply unit to provide the developing agent to the developing device, the method comprising:
- detecting a remaining amount of the developing agent in the developing agent container;
- and
- changing a driving rate of the supply unit when the detected remaining amount of the developing agent is less than a predetermined level.
An image forming apparatus comprising:
- a developing device to provide a developing agent to an image carrier to form an image;
- a developing agent container to store the developing agent and to provide the stored developing agent to the developing device;
- and
- a controller to control a supplied amount of the stored developing agent to the developing device to be substantially uniform during a unit time when the stored developing agent is provided to the developing device from the developing agent container.
A developing agent container usable with an image forming apparatus, comprising:
- a container casing to contain stored developing agent;
- a container docking part coupled to the container casing to output the stored developing agent;
- a detecting member to detect a remaining amount of the stored developing agent in the container casing;
- and
- a supply unit to provide the stored developing agent to the container docking part, the supply unit to increase in a driving rate when the remaining amount of the stored developing agent in the container casing is less than a prescribed amount.
