Title:
DEVELOPING APPARATUS AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2007114322
Kind Code:
A
Abstract:

To provide a developing apparatus capable of preventing image defect and the deterioration of members due to pulverized carrier.

Regarding the developing apparatus 40 where the developer containing the toner and the carrier is carried to an image carrier on which an electrostatic latent image is formed, a capturing means for capturing the pulverized carrier is formed on the inside surface of the developing apparatus 40. By having such the constitution, the carrier pulverized with the impact by the mechanical force in the developing apparatus 40 enters the developing apparatus 40 and remains in the place for a while, consequently, the quantity of the pulverized carrier among the whole carrier is reduced in the developing apparatus 40. Consequently, the quantity of the pulverized toner shifting to the image carrier is reduced, then, the image defect and the deterioration of the member can be prevented. Such a failure is suppressed that the pulverized carrier generated in the developing apparatus shifts toward the image carrier, then, the characteristics of the image forming apparatus can be maintained over a long period.
