OPTICAL WRITING IMAGE FORMING APPARATUS, CONTROL DEVICE FOR OPTICAL WRITING IMAGE FORMING APPARATUS, AND OPTICAL WRITING DISPLAY MEDIUM INITIALIZATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent deterioration of image quality in repeated image writing processing and initialization processing by continuous light irradiation by reducing charge accumulation in a photoconductive layer. SOLUTION: When a display medium 1 is initialized, charges to be accumulated on a CGL in application of negative electrode voltage is reduced by performing positive electrode voltage application+reset light irradiation→negative electrode voltage application+reset light non-irradiation so that the decrease in reflectance during continuous repeated driving is reduced.
