摘要： An image forming apparatus which repeats image create/transfer processing while rotating a photosensitive member and a transfer medium in a sub scanning direction and thereafter transferring the toner image onto the transfer medium, for a plurality of toner colors which are different from each other, to thereby lay toner images in respective toner colors over each other on the transfer medium and accordingly form a color image. The apparatus corrects transfer start positions of toner image in at least one or more toner colors out of the plurality of toner colors based on a registration control amount which is necessary to correct relative registration deviations among toner images on the transfer medium.

摘要： An image forming apparatus comprises: a latent image carrier which carries an electrostatic latent image; a developing unit which visualizes with toner the electrostatic latent image carried by the latent image carrier and forms a toner image; an intermediate transfer medium to which the toner image is transferred from the latent image carrier and which rotates and transports the toner image to a predetermined transfer position and transfers the toner image to a recording medium; a cleaner which abuts on the surface of the intermediate transfer medium and removes toner which adheres to the surface of the intermediate transfer medium after the transfer to the recording medium; and a controller which, assuming that the direction which is orthogonal to the travel direction in which the intermediate transfer medium moves is a width direction, executes toner accumulating processing during which predetermined toner images are formed as end patch images in end areas of the surface of the intermediate transfer medium which are located on outer side along the width direction relative to an image forming region in which a toner image corresponding to size of the recording medium is formed and the cleaner then removes the end patch images.

摘要： Prior to execution of a printing operation, a print preparatory operation is conducted collectively on all developer cartridges mounted to a developing unit, thereby bringing all the developer cartridges into a printable state. Therefore, even if a residual amount of toner in the cartridge runs too low to continue the printing operation performed using one of plural cartridges mounted to the developing unit, the printing operation is allowed to continue by switching the cartridge to the next cartridge. Hence, a large volume of monochromatic prints may be produced in an efficient manner.

摘要： An image carrier is adapted to support a toner image thereon. A circulating intermediate transfer member is brought into contact with the image carrier to form a primary transfer position at which the toner image is transferred onto the intermediate transfer member. A secondary transfer member is brought into contact with the intermediate transfer member to form a secondary transfer position at which the toner image on the intermediate transfer member is transferred onto a recording medium passing therebetween. A gate roller pair is adapted to nip the recording medium therebetween at a nipping position and to convey the nipped recording medium toward the secondary transfer position. A cleaning blade is retractably brought into contact with the intermediate transfer roller to scrape off toner remaining on the intermediate transfer roller. A conveyance speed of the recording medium at the nipping position is faster than that at the secondary transfer position. The cleaning blade is retracted from the intermediate transfer member until when a trailing end of the recording medium passes through the nipping position, in a case where the recording medium has a stiffness greater than a prescribed level.

摘要： In an image forming apparatus capable of selectively carrying out a color print mode or a monochromatic print mode, the individual print modes are carried out as follows. In the color print mode, images are arranged on an intermediate transfer belt 71 with a first spacing d1(a) suited for the color print mode, the first spacing shorter than a second spacing d2(a). Hence, the second spacing d2(a) may be increased by the amount that the first spacing d1(a) is decreased, so that a sufficient time for the changeover of developers 4Y, 4M, 4C, 4K may be afforded. In the monochromatic print mode, on the other hand, adjustment is made to equate the first spacing d1(a) to the second spacing d2(a). This obviates a narrowed sheet spacing.

摘要： An intermediate transfer belt comprises a plurality of layers including a conductive layer, and has a transfer area and a transfer protection area. A CPU 111 sends a control signal to a primary transfer bias generating circuit 116, and applies a primary transfer bias upon the conductive layer of the intermediate transfer medium through a bias applying member 31A. The CPU 111 changes an output value of the primary transfer bias in accordance with a predetermined bias change condition when secondary transfer is not ongoing and when a non-image area, in which there is no toner image transferred on the intermediate transfer belt, such as the transfer protection area is passing the primary transfer part.

摘要： Power transmission members which transmit rotational drive force from a drive source such as a motor, to an intermediate transfer drum is elastically deformed due to a load change which is generated as a cleaning part contacts and moves away from the intermediate transfer drum. Registration control amounts (Ra, Rb and Rc) attributed to the elastic deformation are obtained in advance. Transfer start positions for toner images in at least one or more toner colors out of four toner colors are corrected based on the registration control amounts (Ra, Rb and Rc), whereby registration deviations are suppressed to minimum and a high-quality color image is obtained.
