Title: Production of pulverous magnetic particle for developer
Inventor: AMAGAI YOSHIMI
IPC: G03G9/08
Filed: 1983-06-03
Abstract: PURPOSE:To obtain the uniform electrostatic chargeability and moderate electric resistivity of a magnetic toner and magnetic carrier by mixing a binder resin, magnetic powder and colloidal silica then melting and kneaking the same. CONSTITUTION:The compounding ratio of the binder resin and magnetic powder in pulverous magnetic particles is set at 20:80-80:20. A polymn. resin such as polystyrene, PE and polyether, a condensation resin such as a phenolic resin, urea resin and epoxy resin and the copolymer of these monomers are usable as the binder resin. The magnetic powder having 0.1-3mum average grain size is used, for which pulverous powder of magnetite, chromium dioxide or the like is usable as the magnetic powder. Magnetite is above all inexpensive and usable reliabily. The colloidal silica having <=0.1mu average grain size is used and is compounded at 0.01-10wt% with the magnetic particles by the mixed weight of the magnetic powder and the binder resin. If the magnetic powder, binder resin and colloidal silica are mixed by a dry process in the stage of kneading and melting the same, the fluidity of the mixture is improved and continuous kneading is permitted. The weight average grain size of the magnetic toner and magnetic carrier is made 5-40mum.

Title: Electrophotographic sensitive body
Inventor: YAGI SHIGERU
IPC: G03G5/147
Filed: 1983-06-03
Abstract: PURPOSE:To provide a photosensitive body for electrophotography of an all environment type which has an excellent charge holdability in an electrostatic charging stage and is unaffected by the change in the atmosphere of external environment by using a material formed by drying and curing a soln. contg. zirconium alkoxide in forming the surface layer of a photoconductive layer consisting essentially of amorphous silicon. CONSTITUTION:The construction of a photosensitive body for electrophotography consists of a surface layer 1 consisting of a material formed by drying and curing a soln. contg. zirconium alkoxide, a photoconductive layer 2 consisting essentially of amorphous silicon and a conductive base plate 3. The surface layer 1 blocks the injection of charge from the surface to the inside of the layer 2 in the stage of an electrostatic charging treatment and prevents the direct contact or adsorption of the molecular seeds existing in the environmental atmosphere with or on the surface of the photoconductive layer. And at the same time, the breakage of the characteristic of the layer 2 itself by effect of an external factor is prevented. The desorption of the film constituting atoms contained generally in the layer 2 from the layer 2 is further prevented.
