てあることを特徴とする電子写真用の現像装置。 Electrophotography in which two developing device cases are provided around the photoreceptor and between the exposure section and the transfer device, and a developing roller consisting of a developing sleeve and a magnet is placed in each of the cases in close proximity to each other. In the developing device, the developing roller on the exposure section side is arranged in a direction opposite to the rotational direction of the photoconductor at a portion facing the photoconductor, and the developing roller on the transfer device side is arranged in a section facing the photoconductor. A developing device for electrophotography, characterized in that a doctor blade, at least one of which is made of a non-magnetic material, is disposed between the developing rollers, the rotation direction being set in the forward direction with respect to the photoreceptor.
