Abstract

PURPOSE: To prevent the deviation in the position of an image occuring in the position deviation of transfer paper by applying preliminary revolution further to a transfer drum in such a manner that the 1st transfer is accomplished after the transfer paper has been completely wound on the transfer drum.
CONSTITUTION: The important parts of a developing device 14 are composed of an enclosure member 14A, a developing roller 14B, scooping rollers 14C, 14D, a separator 14E, a doctor 14F, an agitator 14O. With such color copying machine, the 1st preliminary revolution is applied to a transfer drum first, thence the drum is rotated further one turn, and the 1st transfer is started just before the end of the 3 turns. In this state, the transfer paper on the drum does not receive the effect of cleaners and resist rollers and therefore its position is assured and this enables the transfer from the 1st up to the 3rd time to be accomplished without any position deviation.
