Abstract: PURPOSE:To display an image with original clearness and sharpness without phenomena that the image becomes hard to be seen and a ghost image appears, by arranging a ground electrode or a power supply electrode between an input electrode and an output electrode. CONSTITUTION:A ground electrode 12 or a power supply electrode 12 are arranged between an input electrode 12 and an output electrode 12. Between each of the electrodes 12, 12, coupling capacitors 20 of floating capacitance are formed. However, fine input video signals before image processing which have passed the coupling capacitors 20 between input electrodes CVIN, CRIN and a ground electrode G are absorbed in the ground G side. Fine video signals after image processing which are output from output lines CVOUT, CROUT pass the coupling capacitors 20 and are absorbed in the ground G side. Thereby signals before and after processing can be prevented from interfering with each other, and a clear image can be obtained.

Voltage of the same polarity as the charging polarity of the toner is applied to the transport path 4 from a power source 10 to prevent the toner from depositing on the inside surface of the transport path 4. The transport path 4 is constituted by a conductive pipe or pipe 11 etc. of electrical insulation characteristic having an inside wall 12 with conductive treatment. It is also possible to employ such a material which charges to the same polarity to that of the charged charge of the toner by friction with the toner for the inside surface of the transport path 4. In this case, any material which does not charge as largely as to erase the charged charge intrinsic to the toner is selected.
