Filed: 1987-06-29
Abstract: PURPOSE:To always and stably obtain a favorable image by prohibiting the color exchange action or the carrier action of a developing unit at the time of forming a latent image and transferring. CONSTITUTION:The selection (color exchange action) or the carrier action of the developing unit by driving a driving means C is not executed during the time of DELTAt, that means, the latent image forming time (the time of DELTAt1) when the electrostatic latent image corresponding to the original image is formed on the surface of a photosensitive drum and the transferring time (the time of DELTAt2) when the developed image on the surface of the photosensitive drum is transferred on a transfer sheet by a transfer charger. Moreover, during the time of DELTAt, the input specifying the color exchange action or the carrier action of the developing unit is not received. Thus, failures such as the deterioration of the latent image, the fault of synchronism and the deviation in transfer, etc., following vibration are solved, and the favorable image can be always and stably obtained.
