摘要： The present disclosure is directed to suppressing image defects due to variations in the values of currents flowing through respective photosensitive drums during image formation, and reducing the absolute value of a voltage applied when a primary transfer power supply unit applies a voltage of polarity opposite to that during image formation, to primary transfer members. There is provided an image forming apparatus including a transfer member configured to make contact with an inner peripheral surface of a transfer belt, a first power supply unit configured to apply a voltage to the transfer member, a resistance element connected between the first power supply unit and the transfer member, and a diode connected in parallel with the resistance element in a direction in which a current flowing in a first direction is blocked and a current flowing in a second direction is passed.

摘要： An image forming apparatus may include controls for changing a state of the developing roller from a stopped state to a rotating state. The change in state may be used to avoid deterioration of toner and/or a surface of the developing roller. Changes in state may occur at various times including at a timing corresponding to an outside of an image formation area, a timing corresponding to an inside of an image formation area and the like. In one arrangement, a first developing roller may continue to rotate (e.g., during monochrome printing), while one or more other developers are switched between a stopped state and a rotating state. Alternatively or additionally, a roller which is caused to change states may remain stopped between the timing corresponding to a rear end of an image formation area and a timing corresponding to a front end of an immediately subsequent image formation area.

摘要： A method is provided for aligning images on media produced by one or more print engines in an integrated print system. The method includes printing a first pattern of first symbols on a first region of a print medium with a first print engine and printing a second pattern of second symbols on a second region of the print medium with at least a second print engine in a manner to superpose the second pattern on the first pattern. The method further includes measuring a first deviation of the second pattern of second symbols relative to the first pattern of first symbols, recording the first deviation as a first offset distance relative to the first print engine, reporting the first offset distance to a controller of the second print engine, and, using the first offset distance for aligning at least the second print engine relative to the first print engine.

摘要： The color image forming apparatus 1 of the present invention has two intermediate transfer media. With at least two of color images (Y+M+C+K) layered previously, the other remaining images are further layered thereon by a between-intermediate-transfer-media transfer device, and a color image is formed on a transfer material by a transfer material transfer device. The time required until the color image is outputted is shortened. Particularly, an image of single black can be outputted in a shortest time in image formation.

摘要： An image forming apparatus forms a multicolor toner image by superposing a plurality of monochromatic toner images on a transfer material. The apparatus has: a plurality of toner image carriers on which monochromatic toner images of different colors are respectively formed; toner-image-carrier driver for driving all the toner carriers to rotate in a predetermined period; and a position-shift correction quantity detector for determining the position shift quantity of each monochromatic toner image in the multicolor toner image and outputting a position-shift correction quantity corresponding to the detected result. The toner-image-carrier driver controls the period of rotational driving of each toner image carrier in conformity with the position-shift correction quantity.
