PROBLEM TO BE SOLVED: To count pixels in a simple circuit constitution and control an image formation condition with high accuracy. SOLUTION: This image-forming apparatus has a ROS optical part 4 scanning (n) optical beams onto a photosensitive body 50 in accordance with read image signals, a pixel counter circuit 41 counting pixels of an image formed by any one of the (n) optical beams output from the ROS optical part 4, and an operation device 57 controlling a formation condition for the image formed on the photosensitive body 50 in accordance with a counted count of pixels by the pixel counter circuit 41. |
