摘要： In an image forming apparatus, a computing unit computes phase shift amounts A(i) for every correction relative phase angle θ(j) based on an amplitude B of a reference compressional wave αa, an amplitude C(i) of a detection compressional wave α(i), and a relative phase angle φ(i). A setting unit specifies the phase shift amounts A(i), and sets a correction relative phase angle θ(j) corresponding to the specified phase shift amounts A(i). A correction unit corrects, based on the correction relative phase angle θ(j) set by the setting unit, a relative phase shift between a periodic variation in the circumferential speed of a first image bearing member and a periodic variation in the circumferential speed of a second group image bearing member by operationally controlling at least one of first and second drive units.

摘要： An exposure device includes a transmissive member and a shutter. The transmissive member allows passage therethrough of a light beam directed toward a scanning object. The shutter is mounted so as to be pivotable around a pivot shaft between a closed position and an open position. The shutter has a first member and a second member. In the closed position, the first member shields the transmissive member, and, in the open position, unshields the transmissive member so as to allow the light beam to pass through the transmissive member. In the closed position, the second member is positioned above the first member so as to extend at least beyond peripheral ends, including a free end, of the first member.

摘要： A plurality of photosensitive drums are disposed in a sheet transport direction so as to be in contact with a transfer belt and a transfer voltage for transferring toner images on the photosensitive drums onto a sheet transported by the transfer belt is applied thereto. A sensor for sensing a temperature or humidity in the working atmosphere of the image forming apparatus is provided; when a jam occurs, sheet transportation is ceased at a first stage to thereby enable the sheet in the jam to be removed; at a second stage subsequent thereto, transportation of the sheet is restarted; and a transport distance of the sheet is controlled based on a printing ratio of an image formed on the sheet.

摘要： A belt transfer device according to the present invention includes an intermediate transfer belt, a transfer member, a shifter, a detector, and a controller. The transfer member primarily transfers a toner image from an image carrier to the intermediate transfer belt. The shifter reciprocates in specified opposite directions so as to shift the transfer member between a transfer position where the transfer member is in compressive contact with the inner surface of the intermediate transfer belt and a home position where the transfer member is away from the belt surface. The detector outputs a signal representing the position of the shifter. Based on the state of the signal output from the detector while the shifter is reciprocating each time in the opposite directions, the controller determines whether the tensile force of the intermediate transfer belt is proper.

摘要： As a projection extending member is arranged adjacently to a projection, a sensor S1 produces an “ON” state output when an eccentric cam starts turning even in non-printing mode. The time from when the eccentric cam starts turning until sensor S1 changes its output from “ON” to “OFF” becomes longer when a new intermediate transfer belt unit is used than when a used intermediate transfer belt unit is used. The length of this time is measured so as to detect whether the intermediate transfer belt unit is brand-new or old.
