Patent Images
1. A multiple image forming apparatus comprising:
- means for generating color signals;
memory means for storing data corresponding to the color signals;
image forming means for forming images on plurality recording members, said plural recording members being aligned in a subscan direction; and
control means for controlling a data read operation from said memory means such that positional aberration of the images in the subscan direction is corrected, the images being formed by said image forming means,wherein said image forming means transfers the images on each of said recording members onto a common recording medium.
