摘要:
An amorphous silicon photoreceptor for electrophotography having a specific surface roughness is disclosed herein. Also provided are a process for the preparation and/or regeneration of the material and improved methods for electrophotography, which use a special abrasive. The material enables the electrophotography without occurrence of any image blurring under high humidity conditions.
摘要:
A method for producing a magnetic recording medium, which comprises forming, by sputtering, a thin undercoating layer and a thin cobalt alloy magnetic layer sequentially on a substrate, wherein an intermediate electrode is provided in the vicinity of the target to enclose at least 1/2 of the circumference of the sputter erosion end of the target, and at least one of the undercoating layer and the cobalt alloy magnetic layer is formed under such condition that a positive potential relative to the substrate and the grounded portion of the main body of the layer-forming apparatus, is applied to the intermediate electrode.
摘要:
An insulative magnetic toner disclosed herein comprises a magnetic powder, a negative charge control agent, a binder resin and a compound having phenazine ring amorphous-silicon photoreceptor. The magnetic toner according to the invention is effective for preventing the occurrence of picture image blurring under high humidity when used in an amorphous-silicon photoreceptor.
