Abstract
In an image forming apparatus in which multiple photoconductors for corresponding developers of different colors are disposed along a transfer belt or paper conveyance belt, the photoconductors are disposed at intervals that are each an integer multiple of the outer circumference length of the driving roller that drives the transfer belt or paper conveyance belt, and the distance between at least one pair of photoconductors is made different from the distances between the other pairs of photoconductors. As a result, in comparison with when all of the photoconductors are disposed at equal intervals, the degree of freedom in arranging the multiple image forming units that each include an photoconductor can be increased, while color shift among the developed images of the difference colors on the transfer belt or the like is prevented.
