In previous paper, we proposed a new imaging system categorized in an electrolytic electrophotography using a ZnO-resin photosensor. In this system, metallic zinc is electrolytically deposited on the surface of the sensor by imagewste exposure and subsequently a color image is developed by replacing the deposited Zn with colored materials, e.g., 1, 3, 5-Triphenylformazan Red (TF) or Molybdenum Blue (MoBlue). Consequently the photosensitivity is drastically enhanced and more than 0.1 in ASA can be attained. In this report, systematic study on the imaging characteristics has been done in order to obtain its optimum condition. The image reproduction characteristics of this system are presented with the mutual relationships among the quantity of exposed light, the photocurrent of the ZnO-resin layer, the quantity of the deposited Zn and the developed image density. As the conclusion, we point out that further enhancement of the photosensitivity in this system is possible by improvement of the electrolytic condition, e.g., the composition of electrolyte or the surface state of the ZnO-resin sensor.
