Title: Developing method and electrophotographic image forming device
Inventor: KOBAYASHI TETSUYA
IPC: G03G15/08
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To prevent the color mixture of toner by applying a bias voltage to both of fixed and rotary developing means with one developing bias supply and further, transferring the toner from the fixed developing means to an electrophotographic photoreceptor, when an image is not formed. SOLUTION: The toner is discharged by one developing bias supply 16, in such a manner that a developing bias supply is made common. Since only the developing bias supply 16 is made common, the top end part of a color toner latent image is developed by the fixed developing means 6b, because the developing bias is applied to a black developing unit, at the time of executing development with color toner as well. For preventing the development of the top end part, first, the rotation of a developing sleeve is stopped after a developing process with black toner is completed and the developing bias supply 16 is turned on to transfer the toner corresponding to a developing region width in the longitudinal direction of the developing sleeve to a photoreceptor drum 1.  Thus, the fixed developing means 6b applies the developing bias to the color toner latent image, but can eliminate the black toner used for developing from the surface of the developing sleeve.

Abstract: PURPOSE:To improve the S/N of a signal extracted from an output converter by surrounding an upper part of a piezoelectric substrate around a propagation path of a surface acoustic wave, an input converter and the output converter with a surface acoustic wave absorbing device absorbing the surface acoustic wave. CONSTITUTION:An input converter 2 converting an input signal into a surface acoustic wave and an output converter 3 converting a surface acoustic wave propagated on the surface of the piezoelectric substrate 1 into an electric signal are formed respectively to the left and right side of the piezoelectric substrate 1 at a prescribed interval. The input converter 2 converts the input signal into the surface acoustic wave and most of the converted surface acoustic wave is propagated toward the output converter 3, part of the wave goes away from the propagation line and causes a noise as a reflecting wave. However, the surface acoustic wave or the like deviated from the propagation line is absorbed by a surface acoustic wave absorbing device 4 formed around the propagation line of the surface acoustic wave and both the converters 2, 3. Thus, no reflecting wave is caused and the S/N is improved.
