Abstract:
1. An image forming apparatus comprising: a plurality of image carriers that are rotated in the same direction in synchronization with one another, wherein each image carrier within the plurality of image carriers has a circumference associated therewith; a first detector for each image carrier within the plurality of image carriers that detects a predetermined position on the circumference of the respective image carrier; a memory that stores a phase difference for each image carrier within the plurality of image carriers, the phase difference being between the respective predetermined position and a respective eccentric position on the circumference of each image carrier within the plurality of image carriers; and a controller that controls the eccentric positions on the circumferences of the image carriers to coincide in rotational position with one another by using the phase differences stored in the memory, thereby preventing misregistration, wherein the plurality of the image carriers comprises: wherein the controller comprises:
