ことを特徴とする液晶シヤツタ式記録装置。 a liquid crystal shutter panel having a moving photoreceptor, charging means for charging the photoreceptor, and a large number of microshutters arranged in a main scanning direction perpendicular to the moving direction of the photoreceptor and opening and closing according to recording signals;
A light source that emits light to the liquid crystal shutter panel is provided, and the light from the light source is transmitted or blocked by the microshutter and the transmitted light is irradiated onto the photoreceptor, thereby producing static light consisting of high and low potentials on the photoreceptor. In a liquid crystal shutter recording device that performs optical recording by forming an electrostatic latent image, light from the light source is constantly transmitted through an end of the liquid crystal shutter panel in the main scanning direction, and a low potential area is formed on the surface of the end of the photoreceptor in the main scanning direction. a blank shutter forming the low potential region, and a potential sensor for detecting the potential of the low potential region, and adjusting the amount of light emitted from the light source according to the difference between the potential detected by the potential sensor and a predetermined reference potential. 1. A liquid crystal shutter type recording apparatus comprising: a light amount control means for correcting and controlling the potential of the low potential portion of the photoreceptor so that it becomes approximately the reference potential.
