摘要： A separating corona discharger 40 is provided with a first separating discharge wire 42 and a second separating discharge wire 43. The wire diameter of the first separating discharge wire 42 is set to, for example, 60 .mu.m, and the wire diameter of the second separating discharge wire 43 is set to, for example, 100 .mu.m. The first separating discharge wire 42 and the second separating discharge wire 43 are connected in parallel to an AC high-voltage power supply of a constant current type at the offset current. Accordingly, a large number of minus current components flow from the AC high-voltage power supply 46 into the discharge wire 42 having a small wire diameter from which discharge having minus components is easily induced, to obtain a desired distribution of a discharge having a large number of minus current components.

摘要： A radiator plate is formed in a slender shape of which the length is such that a plurality of heat emitting elements are attached to the radiator plate arranged substantially in one row at necessary spatial intervals. The printed circuit board is also formed in a slender shape of which length corresponds to the length of the radiator plate. The power input unit is disposed at one longitudinal end of the slender printed circuit board, and the power output unit is disposed at the other longitudinal end of the slender printed circuit board. Accordingly, the power circuit device may be incorporated in apparatus such as an electrophotographic copying apparatus within a vacant space therein, making efficient use of such space. Thus, the apparatus requires no special space for housing the power circuit device. This enables reducing of the dye of the apparatus in its entirety. Further, the power input unit and the power output unit are sufficiently separated from each other on the printed circuit board. This reduces the interference of the power input unit and the power output unit with each other, resulting in reduction in power noise.

摘要： An apparatus for developing a latent electrostatic image comprises a developer receptacle containing a developer composed of carrier particles and toner particles, a developer applying mechanism for holding on its surface a part of the developer in the developer receptacle and applying it to a latent electrostatic image to be developed, a toner receptacle containing toner particles, and a toner supplying mechanism to be selectively operated to supply toner particles to the developer in the developer receptacle from the toner receptacle. A detector detects the electrical conductivity of the developer in the developer receptacle. The apparatus further includes at least one of (a) a toner exhaustion signal producing device which, when the electrical conductivity of the developer detected by the detector exceeds a predetermined toner exhaustion reference value, produces a signal showing that the toner particles contained in the toner receptacle have been exhausted, (b) a carrier degradation signal producing device which, when the electrical conductivity of the developer detected by the detector falls below a predetermined carrier degradation reference value, produces a signal showing that the carrier particles in the developer have been degraded, and (c) a toner supplying signal producing device which, when the electrical conductivity of the developer detected by the detector exceeds a predetermined toner supply reference value, produces a signal for operating the toner supplying mechanism and a carrier degradation signal producing means which, when the toner supplying signal producing device does not continue to produce the signal in spite of the fact that the latent electrostatic image has been developed a predetermined number of times, produces a signal showing that the carrier particles in the developer have been degraded.
