摘要： A recording apparatus includes an electrostatic image support and a fixing device. The toner image formed on the electrostatic image support is transferred onto a copy paper, and the copy paper is separated from the surface of the electrostatic image support and then fed to the fixing device to fuse the toner image, for example by heat. A device is provided for distinguishing the relation in the length between the distance (A) from the separating position at which the copy paper is separated from the electrostatic image support to the fixing position of the fixing device, and the length (B) of the copy paper in the transport direction. A control device controls the relative circumferential speeds of the electrostatic image support and the copy paper transport apparatus provided inside the fixing device as a function of the distinguished relation between said lengths (A) and (B).

摘要： A method of controlling image density in an electrophotographic copying machine includes operating a first detector to measure the density of a blank region on a photosensitive member, operating a second detector to measure the density of a reference toner image formed on a portion of the blank region, comparing the measured densities of the blank region and the reference toner image, and controlling the density of a developed image of an original in accordance with the results of the comparison. An apparatus in accordance with the invention includes a pair of optical density detecting sensors positioned in opposition to the photosensitive member and in juxtaposition to each other in the direction transverse to the direction of movement of the member.

摘要： In a copying apparatus having a photosensitive member such as a drum, good reproductivity and image density results from applying a proper charging potential to the photosensitive substance on the drum. The optimum charging potential for each drum can be predetermined and a code or indicia representative of such optimum potential may be attached or otherwise appended to the drum. This code is read by a suitable sensor which in turn controls the charging potential applied to the drum.
