Abstract: An image forming apparatus is controlled such that the amount of heat supplied to an outer surface recording sheet to be placed onto an outer surface of a book document for fixing a toner image thereon is greater than an amount of heat supplied to each of the other recording sheets to be placed onto an inner side of the book document for fixing a toner image thereon.

Abstract: A belt-conveyor device includes a detecting unit that detects a belt position in a width direction of the endless belt for a plurality of times within more than a cycle of the endless belt, the width direction being a direction orthogonal to direction of travel of the endless belt; an average calculating unit that calculates an average belt position from the belt positions detected by the detecting unit; a storing unit that stores therein a plural sets of correction values and belt positions; and a meander correcting unit that corrects meander of the endless belt based on a correction value that corresponds with the average belt position in the storing unit.

Abstract: A belt conveyor includes: an endless belt that is looped over a plurality of rollers, the plurality of rollers including a drive roller and a meandering correction roller; a drive unit that rotates the drive roller to drive the endless belt; a meandering correction unit that adjusts an inclination of the meandering correction roller to correct meandering of the endless belt in a width direction thereof; a plurality of position detection units that detect positions of the endless belt in the width direction thereof and output detection signals; and a meandering correction control unit that selectively uses the detection signals from the plurality of detection units to control the meandering correction unit.

Abstract: A sheet conveying apparatus includes: a gate member configured to selectively block a sheet conveyance path thereby providing a structure against which to locate a leading edge of a sheet of an image-bearing medium; resist rollers provided upstream in a sheet conveyance direction vis-à-vis the gate member and configured to convey the sheet downstream to the gate member in the sheet conveyance direction; a detector provided downstream in the sheet conveyance direction vis-à-vis the gate member and configured to detect misalignment at an edge portion of the sheet in a sheet width direction perpendicular to the sheet conveyance direction; a moving mechanism, including a motor, configured to move the resist rollers in the sheet width direction; and a controller configured to change control the moving mechanism by changing a drive mode and a rotation speed of the motor in accordance with a sheet misalignment amount detected by the detector.

Abstract: In a printing apparatus in which a sheet handling device for conducting plural kinds of post processing is connected to a subsequent stage of an image forming device, a plurality of sheet feeding apparatuses disposed in the sheet handling device have a sheet residual amount detecting sensor and a sheet exhaustion detecting sensor. When the sheet residual amount detecting sensor detects that the number of sheets in an inserter is smaller than a predetermined number, the image forming device transports a sheet after it is confirmed by the sheet exhaustion detecting sensor that a sheet remains in the inserter.

Abstract: In an image forming unit system, a sheet handling unit having a fixed sheet carrying-in rate is connected to an image forming unit having a sheet ejection rate controlled variably so that stable sheet carrying can be achieved. The sheet carrying rate (VF) of a sheet carrying-in roller pair (26) provided in a sheet handling unit (2) is defined to be higher than the sheet carrying rate (VU and VD) of a sheet ejection roller pair (16) provided in an image forming unit (1). The pressing force (F2) between the rollers of the sheet carrying-in roller pair is defined to be smaller than the pressing force (F1) between the rollers of the sheet ejection roller pair.

Abstract: A first fundamental electrical element array which has a plurality of columnar, fundamental electrical elements with opposite wire leads, and in which the fundamental electrical elements are electrically and mechanically connected at one wire lead to a conductive bar at predetermined intervals so that they lie side by side in a common plane, and in which the other wire leads of the fundamental electrical elements serve as terminals for connection with a printed-circuit board. A second fundamental electrical element array which has a plurality of columnar, fundamental electrical elements with opposite wire leads and at least one lead wire, and in which the fundamental electrical elements are electrically and mechanically connected at one wire lead to a conductive bar at predetermined intervals together with the lead wire so that they lie side by side in a common plane, and in which the other wire leads of the fundamental electrical elements serve as terminals for connection with a printed-circuit board.
