摘要： An apparatus for developing a latent electrostatic image formed on a photoconductive recording material in a dry type electrophotographic copying machine typically employing a one-component type developer comprises a conductive electrode held in contact with the developer. The electrode is connected to a power source through a switching device and serves to charge the developer to a predetermined polarity with a predetermined potential before the latent image is developed. In this way, the latent image can be developed selectively as either a normal image or a reverse image quite easily.

摘要： An exit blade is arranged on a downstream side of a transfer nip formed between a photosensitive element and a primary transfer roller, with an intermediate transfer belt being put therebetween, and brought into contact with an internal surface of the intermediate transfer belt. A neutralizing bias of the same polarity as that of the toner is applied to the exit blade, rather than a primary transfer bias voltage.

摘要： A transfer device for use in an image forming apparatus includes at least two belt members constituting a secondary nip portion therebetween. The transfer device electrostatically transfers a toner image from one of the belt members onto a recording medium when the recording medium passes through the secondary nip portion. The transfer device includes a mechanism that supports the belt members such that the secondary nip portion is substantially linear; and a bias applying member that applies a secondary transfer bias at a substantially center portion of the secondary nip portion.

摘要： When a steering angle dakaku is equal to or smaller than ±15° (S22), the steering angle dakaku is integrated to calculate an integrated value dakaku_sum (S24). When the integrated value dakaku_sum is within a set range (S25, S26), a road-shape-based wakefulness correction coefficient R_hosei is set at 0.5 (S28). Any erroneous determination of wakefulness attributable to a road shape is prevented by correcting wakefulness H for evaluating wakefulness by decreasing it using the road-shape-based wakefulness correction coefficient R_hosei.
