Abstract

PURPOSE:To form particles on a particle supporting body to a single layer by providing a particle removing roller opposed to the particle supporting body, and a cleaning electrode opposed to the particle removing roller, and impressing a prescribed voltage. CONSTITUTION:The surface of a photosensitive layer 10b is electrostatically charged to negative by a corona electrifier 12, by a rotation of a photosensitive drum 10, and when it reaches a position opposed to a lower opening part 13a of a hopper 13, particles 11 are attracted and made to adhere onto a photosensitive layer 10b. When particles of a lot of layers on the photosensitive layer 10b reach a position opposed to a removing roller 15, the particles are attracted to the particle removing roller 15 by the positive potential impressed to the photosensitive drum 10, and only a single particle layer is left on the photosensitive layer 10b. As the removing roller 15 rotates, the particles are attracted to a cleaning electrode 16 which is opposed to the removing roller 15 and to which the positive potential is impressed, and most of particles are collected into the hopper 13.

There are methods such as applying vibration to the support to cause particles with weak adhesion to fall. These methods are
In order to completely remove unnecessary particles without affecting the necessary particles that should remain on the support, delicate adjustments are required in the way air is blown and the way vibrations are applied, and in order to obtain a good image. is technically extremely difficult.

を除去する現像装置を提供するものである。Unfortunately, because the blade and dielectric are constantly in friction, the blade end face and the dielectric surface are easily damaged, and scratches on the dielectric surface will affect the electric field distribution in the area where the dielectric and the support face each other. This can result in non-uniform electric field distribution, which can affect the image, and can also affect the lifespan of the blade or dielectric itself. Furthermore, there are -1- particles that are not completely removed by the blade and remain on the dielectric material, but when they pass through the corona charger as the dielectric material rotates, they are charged and spread, so that the dielectric material and support are When the size of the opposing part reaches , the electric field in this part attracts the chair toward the support, and the chair falls onto the support, which may hit the necessary particles and disturb the image.Object of the Invention SUMMARY OF THE INVENTION An object of the present invention is to provide a particle removal device for single-layer layering or development, which overcomes the drawbacks of the prior art. In other words, it is a device that removes particles from the second layer and above, which have a weak static adhesion to the support, from among particles dispersed in multiple layers on a charged support, and forms the particles on the support into a single layer. This process is especially essential for image forming methods using light-transmitting particles. Another object of the present invention is to provide a developing device that selectively leaves particles in accordance with an electrostatic layer image formed on an electronic intuitive light body or an electrostatic recording body and removes other unnecessary particles.

れる。FIG. 5 is an explanatory diagram of the behavior of the particles 11 when a semiconductor such as instant lead oxide is used for the outer peripheral portion 15b of the particle removing roller 15. Forming a conductive film such as CuI on the surface of the particles 11,
When using a semiconductor such as zinc oxide for the outer peripheral portion 15b, 1
Compared to the case where a normal dielectric material is used for 5b, particles are more easily attracted even if the same electric current f☆ is applied to the cleaning electrode. Although the detailed cause of this is unknown, it is presumed as follows.

くなると考えられる。In a normal dielectric, particles attached to the outer peripheral part 15b carry a negative charge when they are attracted from the photosensitive layer 10b, so when they face the cleaning electrode 18, they are attracted again according to the electric field there. However, the attractive force depends on the charge l remaining on the particle at that time. On the other hand, in the case of semiconductors such as zinc oxide, the situation seems to be as follows. In the state where the particles 11 have arrived at the outer peripheral part 15b, the CuI of the particles
It is generally considered that the zinc oxide of the outer peripheral portion 15b forms a PN junction. Since it is difficult for positive electricity to be injected from the outer periphery 15b to the particles having negative charge from the photosensitive layer 10b and in contact with the outer periphery 15bllIC, the outer periphery 15b and the support 10
The particles become negatively charged in the electric field between b and 11, but when they come to the part facing the electrode 18, they receive an electric field opposite to the previous one, so the outer peripheral part 15b is oxidized as shown by the arrow. Injection of negative charge from the zinc to the CuI of the particles occurs and the force with which the particles are attracted to the cleaning 7E electrode 18 becomes stronger. Therefore, it is thought that particles are more easily removed even if the electric field strength is the same.
