    摘要: A color printer has means for setting toner image forming areas in the paper sheet convey direction in respect of respective colors, means for detecting a reference position on a photosensitive belt, and image formation start position setting means responsive to the reference position to set a toner image (electrostatic latent image) formation start position in the rotation direction of the photosensitive belt. When the paper sheet length is longer than the outer peripheral length of an intermediate transfer member, the image formation start position setting means sets, for colors other than the final color, a printing area which is shorter than the outer peripheral length of the intermediate transfer member and sets, for the final color, a printing area which begins immediately after a seam position of the photosensitive belt and conforms to the paper sheet length. Through the above setting, when toner images of two colors are superposed to print a color image, the printing area of the final color can be set to a desired range in the paper sheet length direction regardless of the outer peripheral length of the intermediate transfer member, thereby improving the printing speed and preventing degradation of quality.

    摘要: An electrophotographic imaging apparatus includes a toner image holding body, a transcription unit for transcribing the toner image on the toner image holding body onto a recording medium, and a conveyor for conveying a recording medium toward the toner image holding body and transcription unit. A judging device will judge whether printing is of a first page or not and if it is decided that printing is to be performed on a first page, a first measuring device will measure the electrical characteristic of the toner image holding body prior to the feeding of a recording medium and a transcription voltage will be set depending of this measured result. Thereafter, the recording medium will be conveyed toward the transcription unit where the electrical characteristics of the non-printing region on the recording medium will be measured via a second measuring device and the transcription voltage will be further adjusted. If it is judged that the recording sheet is not the first sheet, only the second measuring and adjusting will be performed. In this manner, transcribing of a toner image can always be performed regardless of the kind of paper being used and/or changes in the environment (temperature, humidity) and a high transcribing efficiency can be attained.

    摘要: The present invention relates to a desk-top type color electro-photographic apparatus which is easy in use, small in size and light in weight, wherein maintenance such as changing its photosensitive member can be performed by a user and color adjustment is performed with high accuracy of less than 100 .mu.m. Developing units for four colors are placed in a rank, a single endless-belt-shaped photosensitive member being placed below them to form an approximately oval shape, the photosensitive member being touched with a transfer member on its major axis side to transfer each color of images. In addition to this, the photosensitive member is employed a cartridge type for easiness of user's maintenance and constructed such that highly accurate positioning between the body of apparatus and the cartridge can be performed. Effect of the eccentricity of pulleys is decreased by means of making the pulleys wrapped with the photosensitive member have the identical diameter and making the diameter of the transfer member integer times as large as that of the pulley.

    摘要: A method of recording a color image in such a manner that two toner images of different colors are formed on the basis of video signals supplied from an information processor for producing different colors, and the toner images are transferred to a sheet of recording paper so that the toner images overlap each other, is disclosed, in which method video signal portions for forming contiguous toner images of different colors at a recording position are extracted from the video signals, and one of the video signal portions is extended so that the toner image based upon the video signal portion is enlarged in the direction of the boundary between the contiguous toner images based upon the video signal portions, to prevent a gap having the ground color of the recording paper from generating between the contiguous toner images even when one of the contiguous toner images is spaced apart from the other toner image.
