摘要： An image forming apparatus having deflection scanning type and line type exposing devices and first and second developing devices arranged around a photoconductive element, so that parts around the photoconductive element are arranged with ease to promote the miniaturization of the apparatus. The exposing devices are selected based on the principle that the image quality is enhanced for an image of particular color and is lowered for an image of another color expected to be printed less frequently. Specifically, the deflection scanning type exposing device forms the image of the particular color, and the line type exposing device which has an inherently long optical path and simple structure forms the image of another color. Fans are provided to produce cooling air flow to the line type exposing device and to draw out toner dirt and ozone produced by the charger associated therewith. The line type exposing device and the associated charger are electrically insulated from each other and mounted in a common casing. Cleaning elements are provided to clean the charger and the line type exposing device during withdrawal of these elements from the photoconductive element.

摘要： A bicolor image forming apparatus having first and second exposing means and first and second developing means arranged around a photoconductive element. The first and second developing means are implemented as a deflection scanning type and a line type, respectively. Parts around a photoconductive element are arranged with ease to promote the miniaturization of the apparatus. This stems from the principle that the image quality may be enhanced for an image of particular color and lowered for an image of another color expected to be printed less frequently. Specifically, the apparatus has deflection scanning type exposing means for forming the image of particular color, and line type exposing means which has an inherently long optical path and simple structure for forming the image of another color.

摘要： An electrophotographic copier, facsimile machine, laser printer or similar image forming apparatus for reproducing an image on a paper sheet by transforming an image signal representative of the image into an image forming signal by pulse width modulation, causing a spot beam in the form of a laser beam which is modulated by the image forming signal to scan a photoconductive element to form an electrostatic latent image thereon, developing the latent image to render it visible, and transferring the visible image to a paper sheet. The laser beam output, the set pulse widths of the image forming signal (beam turn-on times) and the bias voltage for development are changed in association with the deterioration of the laser beam power and the sensitivity of the photoconductive element.

摘要： In a folding-order image forming apparatus, image data provided by reading an original image are stored to a page memory. When a copy is made in an electrostatic photographic process in accordance with the image data, the read image data are processed to divide the original image into a plurality of divisional images. Required images with respect to the divisional images are rotated, rearranged and outputted by the operation of a page memory control circuit in accordance with a divisional number of a recording image, etc. Thus, the images are formed in an opening shape by folding or cutting a sheet of recording paper along a divisional boundary of images thereon. The image forming apparatus generally has an image signal memory for storing a digital image signal, a memory region controller for controlling an operation of the image signal memory in a memory region thereof and an image rotational processor for rotating an image by judging the necessity of rotational processing of an image every memory region of the image signal memory.
