Electrostatic latent images are developed by closely positioning a developer carrying member having on a surface a developer composed of fine particles containing an organic semiconductor and being insulating at a normal state adjacent to an electrostatic latent image bearing surface in such a manner that the surface provided with the developer of the developer carrying member facaes the electrostatic latent image bearing surface, and thereby electric charges which are opposite in polarity to the electric charges of the electrostatic latent images being injected into the developer from the developer carrying member by an electric field formed between the electrostatic latent image bearing surface and the developer carrying member and the electrostatic latent images being developed by the developer.
摘要:
A process for development comprises arranging an electrostatic image bearing member having electrostatic images on the surface and a developer carrying member at a predetermined space, an insulating magnetic developer containing 10-50% by weight of magnetic toner particles 20-35 microns in size being carried on the developer carrying member in a thickness thinner than the predetermined space, and transferring the insulating magnetic developer to the electrostatic image bearing member in the presence of a magnetic field.According to this process for development, there can be produced developed images of high fidelity, high density and high resolution and free from fog.
摘要:
A layered ruthenic acid compound is converted to a protonic layered ruthenic acid hydrate, which is then converted to a layered alkylammonium-ruthenic acid intercalation compound to obtain a colloid containing ruthenic acid nanosheets having a thickness of 1 nm or smaller. Thereby, a ruthenic acid nanosheet is obtained.
