Abstract

PURPOSE:To attain development without image blur by providing a fiber vibrating means and preventing a nonmagnetic developer from securely clogging and attaching to the fiber of the aginating and conveying member of a developer. CONSTITUTION:After a developing step is repeated many times, a nonmagnetic toner 34 stagnates between plural fibers 42 of a fur brush roller 40, and is gradually accumulated to result in sticking and clogging. Accordingly the agitating and conveying functions of the fur brush roller 40 are damaged. To prevent said disadvantages, the fiber vibrating means 45 is provided, and is constituted such that the fiber 42 is abutted on a comb-line member on the way of the rotating route of the rotated fiber 42 to vibrate the fiber. As a result, due to the vibration of the fiber 42, the nonmagnetic stagnating and built-in toner 34 is scraped away, whereby the clogging of the fur brush roller 40 can be prevented.

[Technical background of the invention and its problems] Jumping development has conventionally been provided as an electrophotographic development method using a -component developer.

Jumping development is a method in which a single layer of toner formed on a sleeve on a developer carrier is not brought into direct contact with the electrostatic image holding surface of the image carrier, but the toner is selected onto the electrostatic image holding surface by the electric field of the electrostatic image. This is a method of developing by letting the film fly over the surface. According to this method, the toner layer and the electrostatic image holding surface are developed in a non-contact manner with a gap between them, so there are advantages such as the ability to form an image with less background fog.

このような−成分現像剤は非磁性と磁性とに区分される
Such -component developers are classified into non-magnetic and magnetic.

In the method using a magnetic developer, in order to form a single layer of toner on the sleeve, a multi-pole macnet must be placed inside the sleeve, and a magnetic blade or the like is required to regulate the thickness of the toner layer on the sleeve. The drawback is that the developing device is costly. Also, because it uses magnetic powder, it is not suitable for color river edges.

On the other hand, the non-contact developing method using a non-magnetic developer can be said to be an ideal developing method that solves all the above problems, but since it uses a non-magnetic toner, it is difficult to supply the toner onto the sleeve. If stirring is not performed sufficiently, images tend to become blurred due to poor toner transport, and image formation tends to become unstable.
