    摘要： A color image forming apparatus of the present invention charges the surface of a photoconductive belt with a charger, exposes the charged surface with an exposing unit to form a latent image, develops the latent image with a developing unit to thereby form a corresponding toner image, repeats such a process a plurality of times to form toner images of different colors on the belt one above the other, and transfers the resulting composite color image to a recording medium with an image transferring unit. At least a second-color and successive developing units each are implemented as an electrostatic developing unit including an electrostatic toner conveying device having a number of electrodes arranged at preselected small intervals in a direction of toner conveyance and each extending in a direction substantially perpendicular to the above direction. Voltages are applied to the electrodes such that a traveling-wave electric field for electrostatically transferring the toner and an electric field for development for causing the toner to electrostatically move toward the latent image are formed.

    摘要： An abnormality determining apparatus is capable of avoiding mistaken determinations due to the normal value of information obtained by an information obtaining unit differing according to the content of specific information such as the operating mode setting, and deterioration of the determination precision due to a change in the user of a detection subject. The abnormality determining apparatus comprises an information storage unit for storing normal index information serving as an index of a normal state of the detection subject, an information obtaining unit for obtaining a plurality of types of information, and an abnormality determining unit for determining the presence of an abnormality in the detection subject on the basis of the normal index information stored in the information storage unit, and the information obtained by the information obtaining unit. The information storage unit stores a plurality of normal index information having different values. The abnormality determining unit selects, at a predetermined timing, normal index information to be used to determine the presence of an abnormality in the detection subject from the plurality of normal index information.
