Abstract
A system has a first electrode, a second electrode, a photosensitive member located between the first and second electrodes, a recording member located between the first and second electrodes, and an optical shutter. In this system, light having information to be recorded is applied to the photosensitive member. The light information is recorded on the recording member. An exposure amount of the light with respect to the photosensitive member is set by setting a time during which the optical shutter remains open. A drive voltage of a predetermined variation is applied between the first and second electrodes during the recording of the light information on the recording member. The predetermined voltage between the first and second electrodes is controlled in response to a sensed intensity of reference light which passes through the photo-modulation member.
