    • A porous photosensitive unit has a transparent conductive layer formed on a surface of a transparent substrate. A photoconductive layer is formed on a surface of the transparent conductive layer. A porous insulating layer formed on a surface of the photoconductive layer has a plurality of holes for holding conductive color particles. The plurality of holes includes a first hole and the adjacent second and third holes. An upper or screen electrode is formed on a surface of the porous insulating layer except where the holes are formed. The photosensitive unit includes an optical arrangement in which, when a light source emits light to cause conductive color particles to fly out of the first hole only, the light exposes a region, within the photoconductive layer, which substantially coextends with a surface portion of the photoconductive layer that is exposed by the first hole.

    • An image forming apparatus of the present invention includes a particle conveying body made up of a light-transmitting conductive layer, an insulative'screen provided on the conductive layer and formed with a number of pores, and a screen electrode formed on the screen. Photoconductive, colored particles are charged to negative polarity and then caused to fill the pores by an electric field. When the particles in the pores are exposed via the conductive layer, electron-hole pairs are generated in the particles. An electric field of as high as 104 V/cm or above is formed between the conductive layer and the screen electrode and separates the electrons and holes. The electrons leak to the conductive layer and cause the particles to be charged to positive polarity. An electric field formed between a facing electrode positioned behind a recording medium and the conductive layer causes the particles to fly toward and deposit on the medium.

    • A control circuit for video tape recording and/or playback apparatus is coupled to a stationary control head for selectively changing the duty ratio of the control signal that accompanies the recorded video signal and is the same signal that is used to control the servo operation of head drum and capstan motors of the apparatus. Normally, the duty ratio of the control signal is 50%, but the control circuit permits an operator to selectively alter the duty ratio, for example, to 30%, to indicate that the accompanying segment of the recorded video signal is to be edited out, that is, skipped over when the tape is played back. A duty-ratio detector coupled to the control head discriminates the duty ratio of the reproduced control signal, and a system controller automatically changes the mode of the apparatus to advance at fast-forward past those portions of the video signal accompanied by a 30%-duty-ratio control signal.
