摘要： An image forming apparatus having plural developing devices, comprising: a photosensitive member arranged rotatably in one direction and holding an electrostatic latent image corresponding to an original image; a developing sleeve rotatably arranged in each developing device at a position confronting said photosensitive member to transport a developer; a device for simultaneously driving for rotation of each of said developing sleeves in said developing devices; and an adjusting mechanism for adjusting operation of said developing devices so that in a region where said developing sleeves confront with said photosensitive member, a developer packaged density (F) in said developing device arranged at an upstream side in a rotational direction of said member is larger than that of said developing device arranged at a downstream side in the rotational direction of said member, which isF=Vd/Ds,where Vd is an amount of the developer passing between said developing sleeve and said photosensitive member per hour, and Ds is a distance between said developing sleeve of said developing device and said photosensitive member. Then, a high quality image may be reproduced by the apparatus, which has improved reproducibility RSI of density of a reproduced solid obtained by the upstream device and improved reproducibility RLI of density of a reproduced line image obtained by the downstream device.

摘要： An image forming apparatus includes a photosensitive member rotatably supported; an upstream developing device, in a rotary direction of the member, for developing an electrostatic latent image corresponding to a solid image and/or a literal image with an accommodated developer therein; a downstream developing device, in the direction thereof, for developing an electrostatic latent image corresponding to a line image with an accommodated developer in the same color as that in the upstream developing device; a cleaning device for collecting the developer remained on the surface of the member; and a developer transporting device for transporting the developer collected by the cleaning device to the upstream developing device. The apparatus further includes a charging device for charging a specified zone of the surface of the member; an image forming device for forming the latent image on the charged specified zone thereof; a voltage changing device for selecting one of a first developing bias voltage and a second developing bias voltage which is higher than the first developing bias voltage; and a control device for controlling the voltage changing device. By the control device, the first developing bias voltage is applied to the upstream developing device while the latent image on the specified zone of the member passes through a developing region of the upstream developing device and the second developing bias voltage is applied thereto while the specified zone passes therethrough again after the latent image passes therethrough.

摘要： The disclosure relates to a method, using an electrophotographic system, including a first process of transferring the image of an original document to a copy sheet and a second process of transferring a half-tone solid on a specified region of the image on the copy sheet transferred at the first process. Accordingly, for example, when a copy sheet is white, a black toner is used in the first image forming process, and a white toner is used in the second image forming process, a white half-tone solid of the white toner is superimposed on the black toner image. As a result, the black toner image formed on the specified region looks soft half-tone.

摘要： An imaging apparatus includes a toner ejection mode whereby toner stored in a black developing container is completely removed from the developing container by rotating a rotary developing unit at a specific timing and using gravity and the centrifugal force that acts on the toner stored in the black developing container due to this rotation, or using the vibration that acts on the black developing container when the rotation is stopped. In this toner ejection mode, the toner is ejected from the developing container of the rotary developing unit, an image for a single sheet of recording paper is formed on the surface of a photoreceptor drum, and the toner constituting the image transferred onto the surface of an intermediate transfer belt by the photoreceptor drum is then recovered by a belt-cleaning unit.

摘要： In image formation of a black-line image, the image is developed with black toner, and in addition parts of the black-line image corresponding to an intersection between at least two black lines and a middle portion of a black line are developed with toner of at least one of cyan, yellow, and magenta colors overlaid. This makes it possible to prevent central voids in a black-line image. In a black-line image transferred onto a transfer medium by this full-color image forming apparatus, not only are central voids eliminated, but degradation of image quality is also prevented.
