Title: Electrophotographic method
Inventor: ENOKI SHIGEKAZU
IPC: G03G9/08
Filed: 1980-01-24
Abstract: PURPOSE:To enable a toner image to be transferred to a plain paper without  weakening toner charge, by using a one-component type magnetic toner of particle diameter in a specified range, forming conductive paths between a developing sleeve and a photoreceptor, and injecting charge reverse in polarity to an electrostatic latent image to the toner. CONSTITUTION:A magnetic material having 0.5-5mum average particle diameter amounting to 30-70wt% of the total raw material of a toner containing a binder resin is heat-melted and cooled, then pulverized to give a one-component type toner having 8-18mum average particle diameter and 1.8-2.2 true specific density. Obtained toner particle T have magnetic grains larger than conventional ones, and forms a conductive path in the direction X-X, but toner particle T functions as an insulating material in the direction Y-Y due to larger spaces between magnetic grains 11. As a result, a few toner particles form a conductive path between photoreceptor 2 and grounded developing sleeve 6 surrounding fixed magnets 9, and toner T1 is given positive charge reverse to electrostatic negative charge on  photoreceptor 2, thus permitting toner T1 to form a visible image by toner T2 and then, toner T2 to form a transferred toner image of toner T3 by applying an electric field to transfer paper S from the backside.

Filed: 1983-01-21
Abstract: PURPOSE:To desirably carry out torque transmission and braking, by attracting an armature to a rotor by a solenoid coil to transmit rotation of a main shaft and adjusting a spacing of attraction by a coil spring and a screw. CONSTITUTION:When voltage is applied to a solenoid coil 19, an armature 5 is excited by a field core 4 through a rotor 3, and is magnetically attracted to the rotor 3. A pulley 8 connected through a leaf spring 9 to the armature 5 is rotated with the rotor 3 integrally fixed to an output shaft 1 in the same direction, and a driven shaft is rotated through a belt. When application of voltage is stopped, excitation of the armature 5 is released and is separated from the rotor 3 by the leaf spring 9. At this time, a back surface 5a abuts against a flange 13A of a brake cover 13, thereby preventing idle rotation due to inertia. In the event that a spacing of attraction is enlarged by abrasion of opposite surfaces of the rotor 3 and the armature 5, a nut 17 is screwed to slightly move the brake cover 13 to the rotor 3.
