PROBLEM TO BE SOLVED: To provide an image forming device in which a sensor and a peripheral circuit have a simple constitution, which is equipped with an image position deviation measuring means capable of stably measuring the positional deviation without being influenced by the fluctuation of the speed of an image carrier, and which can output a high-quality image free from positional deviation of colors. SOLUTION: An image aligning controller 31 forms on recording paper 7 measurement reference patterns 40 and 41 whose reflection density is changed in accordance with the positional deviation between individual colors, and measures them by a reflection density sensor 13. By using a reflected light quantity-correction value conversion part 52 in the controller 31, correction values for image forming parts 8K to 8C are obtained and set as a correction information signal 39 and transmitted to an imaging control part 32. Based on the correction information obtained from the signal 39, the control part 32 controls the individual image forming parts 8K to 8C by using an imaging part parameter setting signal 28. |
