PCT No. PCT/JP91/00764 Sec. 371 Date Mar. 9, 1992 Sec. 102(e) Date Mar. 9, 1992 PCT Filed Jun. 6, 1991 PCT Pub. No. WO91/19228 PCT Pub. Date Dec. 12, 1991.A charge carrier medium (41) is successively fed to a rotating (or reciprocating) photosensitive material (40) in opposite relation thereto. Making use of a beam or linear slit scanning exposure system or a planar exposure system enabling one frame to be scanned every 1/60 sec., for instance, the exposure timing is allowed to synchronize with the movement of the photosensitive material (40) and the feed of the charge carrier medium (14) to record images successively on the medium by either voltage-applied exposure or short-circuit exposure in which the charge carrier medium is pre-charged, whereby the images can be picked up as moving images. At the same time, the photosensitive material (40) is irradiated with light from the charge-clearing light source (45) to clear it of a residual charged image. Alternatively, such leakage of charges may be achieved by bringing an electrically conductive member into contact with the photosensitive material, charging it uniformly as by d.c. or a.c. discharge, heating it or bringing it into contact with an electrically conductive liquid or vapor, whereby the residual image on the photosensitive material is rapidly decayed to eliminate the influences of the residual image on the photosensitive material, thereby making it possible to obtain electrostatic images of high quality continuously.
