摘要： In a case where there are developers belonging to Life Rank 1 representing a service life substantially as long as that of a fresh developer (Step S501), and the developers includes one which is ready to print (Step S502), it is determined that image formation can be performed without performing a preparatory operation (Step S506). In a case where there is no print-ready developer but a developer which requires an agitation operation of rotating a developing roller by a predetermined quantity (Step S503), the agitation operation is performed on the developer (Step S504) so as to make the developer in a print-ready state. In a case where the developer cannot be made print-ready by the agitation operation, a density control operation for adjusting operating conditions of an apparatus is performed (Step S505). Thus is obviated an unnecessary operation. The developer subjected to a predetermined print preparatory process is used in a printing operation so that an image of good quality may be formed. In a case where no Rank-1 developer is available but a Rank-2 developer, deteriorated to a degree, is available, the same procedure is taken.

摘要： Prior to execution of a printing operation and in parallel with a warm-up operation of the apparatus, a print preparatory operation is conducted only on selected cartridges of cartridges mounted to a developing unit, thereby bringing the cartridge into a printable state. Therefore, even if the residual amount of toner in one of the selected cartridges runs short, the printing operation is allowed to continue by switching this cartridge to the next selected cartridge.

摘要： Power transmission members (91), which transmit rotational drive force from a drive source (81), such as a motor, to an intermediate transfer drum (41D) is elastically deformed due to a load change which is generated as a cleaning part (49) contacts and moves away from the intermediate transfer drum (41D). 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.

摘要： A reference time ts, which corresponds to a period of time a sheet S needs to move passed a detection position P1 where a sheet detection sensor 841 is disposed, is set in advance in accordance with the length of the sheet S. After a time t1 from the start of driving of a gate roller, as the leading edge of the sheet S transported to a nip area N which is between the heater roller 91 and a pressurizing roller 92 arrives at the detection position P1, an output from the sheet detection sensor 841 changes to an L-level. When the transportation of the sheet has been normal, the sensor output returns to an H-level after a reference time ts or a longer time. On the contrary, upon occurrence of a jam J2 that the sheet S has got wrapped around the heater roller 91, the leading edge of the sheet S moves backward, and therefore, a duration tm in which the sensor output is kept at the L-level becomes shorter than the reference time ts.

摘要： Of developers 4a, 4b and 4d which are adjacent to each other on a rotary developing unit 4, the downstream-most developer 4d along the direction D4 of rotations of the rotary developing unit 4 is positioned first at a developing position and a patch image is formed. The rotary developing unit 4 then rotates 90 degrees, and the adjacent developer 4a is moved to the developing position. While the developer 4a forms a patch image, a memory of the developer 4b is updated. After this, while rotating the rotary developing unit 4 by 90 degrees each time, patch image formation with and memory update for the respective developers are carried out.

摘要： An intermediate transfer belt having a plurality of layers including a conductive layer, and having a transfer area and a transfer protection area. A CPU sends a control signal to a primary transfer bias generating circuit, and applies a primary transfer bias upon the conductive layer of the intermediate transfer medium through a bias applying member. The CPU changes an output value of the primary transfer bias in accordance with a predetermined bias change condition when a 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.
