Title: Power circuit
Inventor: EJIRI KAZUYASU
IPC: G05F1/56
Filed: 1984-09-20
Abstract: PURPOSE:To generate a specific voltage speedily at an output terminal in power-on operation by providing plural transistors (Tr) resistances for supplying base currents of those Trs, and capacitors. CONSTITUTION:When an AC input is applied, the base voltage of a Tr3 rises immediately and the TrQ3 turns on immediately, but the voltage of the capacitor C4 is 0V and a TrQ4 is off. Therefore, the emitter output voltage of a TrQ1 is cut off. Then, the capacitors C4 and C3 are charged gradually with currents flowing through resistances R7 and R2, but the TrQ4 is sill off until the voltage of the capacitor C4 attains to the base-emitter on voltage of the TrQ4. Then when the voltage of the capacitor C4 rises up to the base-emitter on voltage of the TrQ4, the TrQ4 turns on and the TrQ3 turns off. Consequently, the emitter voltage of the TrQ1 is raised speedily up to the set value.

Abstract: PURPOSE:To obtain a developer excellent in the rising property of toner electrification and hardly causing toner spent by mixing a carrier having a rugged surface structure, a carrier having no rugged surface structure, and an electrophotographic toner. CONSTITUTION:Two kinds of carriers having a rugged surface structure and having no rugged surface structure are mixed with a specified amt. of toner.

The carrier having no rugged surface satisfies alpha<=1.2, while the carrier having rugged surface satisfies alpha>1.2.
