    摘要: An intermediate transfer drum has at least a drum main body having a volume resistivity of 10.sup.4 to 10.sup.8 .OMEGA.cm, and an insulating layer provided on an outer surface of the drum main body. A first transfer voltage applying roller is provided inside the intermediate transfer drum so as to be opposite to a photosensitive drum and so as to be in contact with an inner surface of the intermediate transfer drum. A transfer roller is provided inside the intermediate transfer drum so as to be opposite to a second transfer grounded roller and so as to be in contact with the inner surface of the intermediate transfer drum. By thus arranging an image forming apparatus wherein image formation is carried out with respect to recording paper through the intermediate transfer drum, an optimal first transfer voltage can be applied from the photosensitive drum to the intermediate transfer drum, while an optimal second transfer voltage can be applied from the intermediate transfer drum to the recording medium. As a result, the first transfer and the second transfer are individually and simultaneously carried out. Furthermore, since the intermediate transfer drum does not become large in size, it is avoidable that the image forming apparatus becomes bulkier, while the lowering of the copying speed can also be suppressed.

    摘要: The present invention is intended to reduce a f.theta. correction error by correcting an error of an object scanning speed which is produced because a reflecting point of a laser beam moves on a polygon mirror. In an inventive laser scanner, laser light emitted from a laser oscillator is condensed into a beam by a condenser lens at first. This laser beam is reflected by a polygon mirror rotated by a scanning section and is reflected again to a photoreceptor by a curved reflecting mirror. A curved profile of a reflecting plane of the curved reflecting mirror in the main scanning direction is formed so as to be asymmetrical on right and left bounding about a scanning center point. Thereby, variation of speed for scanning the curved reflecting mirror by the light reflected by the polygon mirror may be canceled by the curved reflecting mirror and a speed for scanning the object may be fixed almost at a predetermined speed.

    摘要: An image forming apparatus is provided with a photoreceptor, and an exposure device for exposing the photoreceptor based on image data so as to form an electrostatic latent image on the photoreceptor. The exposure device has a plurality of light emitting devices aligned along a main scanning direction of the photoreceptor, the respective light emitting devices having a plurality of luminescence portions, and a light emitting device driver for applying a voltage to the respective luminescence portions so that the luminescence area of the light emitting device increases step by step whenever the applied voltage increases by a predetermined voltage based on the image data. With the arrangement, tone expression is realized in the electrostatic latent image, according to the size of the luminescence area of the respective light emitting devices, which can be controlled by the voltage applied to the respective light emitting devices based on the image data. Accordingly, it is possible to form the electrostatic latent image having many tones on the photoreceptor based on image data accurately and easily.

    摘要: A main controller controls drive of an LSU for irradiating laser light onto a charged photoreceptor, based on control data read from a non-volatile memory. The main controller causes the LSU to irradiate a beam of light onto the photoreceptor so as to form on the photoreceptor an electrostatic latent image corresponding to an image to be formed. A controlling section reads through an image reading section control data from the non-volatile memory at a different timing from a timing at which the main controller controls the LSU. The controlling section controls drive of the LSU based on the read control data.

    摘要: The present invention allows a specific image to be easily changed when using a counter in the case of adding a specific image. A specific image adding section 12 for adding the specific image to inputted image data includes a first counter 15 for deciding positions of a main scanning direction and a vertical scanning direction and a second counter 16 for specifying a form of the specific image. The second counter 16 counts up addresses of pixels counterclockwise with a starting point at one corner on a matrix made up of the main scanning direction and vertical scanning direction. If the first counter 15 counts a predetermined count value, the second counter 16 starts. When a maximum value of the count value of the second counter 16 is equal to or less than a count set value, an image is formed on each of the pixels. The pixel on which the image is formed is changed and the form of the specific image is also changed by changing the count set value.

    摘要: The static latent image formed on the photoreceptor which has been charged, by exposing it to light, is developed through four colors of developing units, i.e., yellow, magenta, cyan and black, forming toner images on the photoreceptor. These toner images are transferred to the transfer drum. Before forming the toner images, a device is provided to correct the measurement value of toner density obtained using the light emitter and photosensor into an exact value. Based on the reflected light from a white-coated area formed on the transfer drum, two levels of the intensities of emitted light are determined. The intensity of received light is compared to the standard value so that the output value from the photosensor corresponding to the toner density is made to approximate the standard value.
