摘要： An image forming apparatus includes a plurality of image carriers, a drive mechanism, a plurality of drive force transmission gears, a phase difference detector, and a shift unit. The plurality of image carriers forms images of separate colors. The drive mechanism including a single drive unit for driving the plurality of image carriers simultaneously. The plurality of drive force transmission gears, provided for each of the image carriers, transmits a driving force from the drive unit to the image carriers. The phase difference detector detects a phase difference in drive speed among the image carriers. The shift unit, provided for each of the plurality of drive force transmission gears, meshes or unmeshes the drive force transmission gear to the drive mechanism. The shift unit is activated to correct any phase difference in drive speed of the image carriers based on a detection result detected with the phase difference detector.

摘要： An image forming apparatus includes an endless belt member; a drive unit moving the endless belt member; a first detecting unit detecting a rotating speed of the drive unit; a second detecting unit detecting an endless transport speed of the endless belt member; and a control unit controlling the rotating speed of the drive unit based on a first detection signal from the first detecting unit or a second detection signal from the second detecting unit selectively depending on a selection condition. Upon selection of the first detection signal in accordance with the selection condition, the control unit corrects the rotating speed of the drive unit using the second detection signal such that an average value of the endless transport speed of the endless belt member approaches a target average value.

摘要： A printer according to the present invention is a so-called tandem-type printer, and has a configuration that a motor gear is directly connected to an M-photoconductor driving gear and an idler gear is directly connected to a Y-photoconductor driving gear and the M-photoconductor driving gear. A diameter of the Y and M photoconductors driving gear, a distance between transfer sections of the Y and M photoconductors, a motor gear input angle, and an idler input angle are set so that an absolute value of a value obtained by subtracting 1 from an ideal amplitude ratio, which indicates a ratio of an ideal amplitude of an eccentric component of the Y-photoconductor driving gear to an actual amplitude of an eccentric component of the M-photoconductor driving gear, is equal to or less than a maximum allowable amplitude ratio.
