Abstract:
1. An image forming apparatus comprising: photosensitive means, each rotatable about a predetermined axis, for forming a color image for respective colors; light exposure means, provided for the respective colors, for forming a latent image corresponding to a line-like image of a predetermined pitch in an axial direction of the respective photosensitive means; developing means, provided for the respective colors, for supplying color developing agents corresponding to the respective photosensitive means for allowing the latent image which corresponds to the line-like image of the predetermined pitch to be developed; transfer means for allowing the developed line-like image of a predetermined pitch for the respective color to be transferred; sensing means, arranged at a predetermined position, for detecting the transferred line-like image formed for the respective color; and adjusting means for, based on the phases of waveforms for the respective colors calculated from the pitch of lines for respective colors which have been detected, relative to the phase of given photosensitive means, adjusting the rotation positions of the other photosensitive means to allow the phases of the other photosensitive means to be substantially matched to the phase of the given photosensitive means.
