摘要： Image forming apparatus provided with a process cartridge including at least a belt-shaped image carrier. A protective cover automatically covers a transfer section of the image carrier installed in the process cartridge, in response to a traveling motion of the process cartridge from a first position in which an image can be formed, to a second position in which the process cartridge can be attached to or detached from the apparatus. The protective cover also automatically exposes the transfer section of the image carrier in response to the input of a power source to the apparatus, or the input of an image forming signal for forming a latent image on the image carrier, or the process of mounting of the process cartridge to the apparatus.

摘要： An image forming apparatus such as an electrophotographic copier and an electrophotographic printer. The image forming apparatus includes: a photoreceptor for forming a toner image on its surface; a charger for charging the surface with a bias voltage, including a DC component and a AC component, through a magnetic brush member which is in contact with the surface; a driving unit for moving both of the surface of the photoreceptor and the magnetic brush member in synchronism; a laser unit for imagewisely exposing a predetermined image area of the surface, which is charged by the charger, so that a latent image is formed on the surface; and a discharge lamp for exposing the surface with light so that the surface is discharged. In such the image forming apparatus, the discharge lamp starts exposing the surface with the light and the bias voltage, with which the surface is charged, is set at substantially 0 volt before the driving starts moving the surface and the magnetic brush member; and the predetermined image area of the surface is charged with the bias voltage, including the DC component and the AC component, after the driving starts moving the surface and the magnetic brush member.

摘要： Color image forming apparatus includes a belt-shaped image carrier stretched and conveyed around rotating rollers on which image exposure is conducted by a plurality of exposure units; and a plurality of step-formed supporting surfaces below the lower surface disposed of the image carrier. The stepped formation of the exposure unit supporting surfaces avoids interference between optical paths of laser beams for image exposure, and facilitates compactness of the apparatus. The belt-shaped image carrier and the supporting surfaces are provided at a relative angle of 5-30 degrees. The color image forming apparatus is also capable of detecting a specific pattern outputted from the exposure units; calculating the differences of positions of the specific pattern as formed by the different exposure units; and controlling the positioning of the specific pattern as outputted by the exposure units, so as to increase the accuracy of the image forming apparatus.

摘要： In a toner image fixing device, there are provided an endless belt being looped up around a heating roller and a conveyance roller, a pressure roller for pressing a sheet having a toner image onto the heating roller with the endless belt intervening between the pressure roller and the heating roller. A sensor is disposed inside the loop of the belt so as to come in contact with the heating roller, for detecting the temperature of the heating roller. The fixing temperature for the toner image is controlled on the basis of the temperature of the heating roller detected by the sensor. A first nip region is formed on a pressing portion located between the heating roller and the fixing roller. A second nip region is formed between the belt and the fixing roller, continuing from the first nip region but without contacting the heating roller.

摘要： In a color image forming machine including a belt-shaped photoreceptor stretched around a plurality of rollers, and a horizontal portion of the photoreceptor being disposed above and in parallel to face a plurality of developing devices, a charging device and a transfer device are disposed to face the photoreceptor at a common position where the photoreceptor is curved around one roller. A cleaning device is disposed to face the photoreceptor at a position where the photoreceptor is curved around the other roller. The charging device is used as a transfer device by changing supplied voltage or is interchangeable with the transfer device by being either slid or rotated between two positions. The photoreceptor, the developing devices and the cleaning device are integrally formed as a cartridge which is detachably mountable to the machine. The photoreceptor is rotated at least five times when a color image is formed by the processes of charging, exposing, transferring and cleaning, and is rotated at least twice when a monochromatic image is formed by the processes.
