PURPOSE:To prevent the mixture of toner and to prevent the mixing colors and the change of elementary color, by a method wherein plural couples of development systems including recording electrodes and magnetic developing devices arranged for color recording are so constituted as to operate independently according to each color. CONSTITUTION:Insulative recorders 3 are respectively separately installed as the first, the second and the third recorders 3a, 3b, 3c corresponding to each development system. The charge of each conductive recorder 3a, 3b, 3c conveyed in the arrowed mark A direction is removed with charge removel corotron 16a, 16b, 16c and the remainder toner of each system the charge of which is removed with each charge removal corotron 16a, 16b, 16c, is recovered to each original developing device with the magnetic force of each developing device 6a, 6b, 6c. |
