摘要： An image forming apparatus includes an image support which supports an electrostatic latent image on a surface of the image support. A developing unit has a developing agent support which retains a developing agent, including a toner and carriers, contained in the developing unit. The developing unit converts the latent image on the image support into a toner image by causing the toner to adhere to the surface of the image support. A developing bias supplying unit supplies a developing bias voltage to the developing agent support of the developing unit, the developing bias voltage being one of a DC bias voltage and an AC bias voltage. A timer measures a non-driven period of the developing agent in the developing unit. A control unit selects one of the DC bias voltage and the AC bias voltage from the developing bias supplying unit based on the non-driven period measured by the timer, and controls the developing bias voltage at an output of the developing bias supplying unit such that the selected one of the DC bias voltage and the AC bias voltage is supplied to the developing agent support.

摘要： A transverse type gas laser oscillator includes a receptacle for containing a gas as a laser medium, a pair of electrodes disposed to be parallel to each other on opposite sides of the receptacle so that an electric field is established for generation of AC discharge when a high-frequency voltage is applied to them, and a pair of permanent magnets disposed so as to form a magnetic field intersecting a direction of the electric field established between the electrodes, or a pair of coils excited by a DC voltage. Consequently, ionization of the gas excited by the electric field is increased by the magnetic field.

摘要： A gas laser device includes a high frequency power source for generating a high frequency output voltage and a pair of electrodes positioned sandwiching a discharge gap through which laser gas circulates. The pair of the electrodes are connected to the high frequency power source for applying the high frequency output voltage across the electrodes to achieve discharge in the discharge gap and to thereby generate laser light. Each of the electrodes includes an electrode element, a capacity coupling control element provided on either side of the electrode element, and a dielectric shell. The dielectric shell surrounds the electrode element and the capacity coupling control element, therefore the discharge occurs between the dielectric shells of a pair of the electrodes. The dielectric constant of the capacity coupling control means is lower than that of the dielectric shell.
