PURPOSE: To form a plurality of images being precisely registered and having perfect contrast. CONSTITUTION: Imagewise exposure at high resolution ROS 32 and AC at an AC scotron 36 are executed at the same time to form four electrostatic balanced (developing impossible) images 42, 44, 46 and 48. Next, the image 42 is made an unbalance (developing possible) image by low resolution ROS 50 and developed by a developer device 52. Similarly the images 44, 46 and 48 are successively developed respectively by low resolution ROS 64 & a developer device 66, low resolution ROS 80 & a developer device 82, and low resolution ROS 90 & a developer device 88. |
