摘要： An image forming device includes a plurality of image formation units each configured to form an image of one of a plurality of colors, and a patch image transfer unit configured to control transfer conditions during transferring a patch group that is a pattern for detecting a position shift and formed on an intermediate transfer belt onto a secondary transfer belt. The patch image transfer unit is configured to transfer patches of at least single color for which a band of transfer efficiency is narrowest, of the patch group, onto the secondary transfer belt under transfer conditions for the color, and during transition to the transfer conditions for the color from other transfer conditions or during transition from the transfer conditions for the color to the other transfer conditions, patches of a color other than the color, of the patch group is transferred onto the secondary transfer belt.

摘要： An image forming apparatus includes a patch forming unit configured to form a patch group containing patch subgroups arranged in a sub-scanning direction. Each of the patch subgroups contains a reference color patch and a color patch of a different color. The reference color patches are shifted from each other in a main-scanning direction. The color patches are shifted from each other in the main-scanning direction. The patch subgroups include reference patch subgroups in each of which the reference color patch covers over the color patch and detection patch subgroups in each of which at least part of the color patch does not overlap with the reference color patch. Center positions of non-overlapping portions of the color patches that do not overlap with the reference color patches in the main-scanning direction are located at substantially a same position in the patch group.

摘要： In a simultaneous multibeam scanning system, composite beams are formed by using two semiconductor laser arrays each of which can singly output a plurality of beams. An optical system is enabled to scan beams of the number, which corresponds to the sum total of output beams of each of laser light sources, in a scanning plane. A stabilization control means for maintaining the interval between adjacent scanning beams at a uniform value is introduced into this optical system.

摘要： An image forming apparatus includes a transfer condition setting device to set a patch image transfer condition under which multiple patch images of respective component colors are transferred from an image bearer onto a recording medium conveyor. The transfer condition setting device sets a prescribed transfer condition that decreases a difference in transfer efficiency of toner between the respective component colors when the multiple patch images of respective component colors are transferred onto the recording medium conveyor below a difference in transfer efficiency of toner between the multiple component colors caused when transferred under the same transfer condition as a multicolor toner image is transferred onto a recording medium. A correcting device corrects an image forming condition to reduce an amount of misalignment caused in the multiple component colors of the multicolor toner image based on times of outputs from a patch image position sensor.

摘要： A semiconductor laser device including an edge-emitting type laser chip having at least three emitting points in one light emitting edge, a sub-mount mounted with the laser chip, and a heat sink bonded to the sub-mount through a solder layer. When R designates a linear expansion coefficient ratio of the heat sink to the sub-mount and D designates a distance between light emitting points at opposite ends in the light emitting edge of the laser chip, materials of the sub-mount and the heat sink and the distance D are set to satisfy the following relation: D≦5.48×R−2.13 A difference between stress acting on one laser element and another in the laser chip due to shrinkage of the heat sink when melted solder is cooled down is reduced so that a difference in light output characteristics between one light emitting point and another can be reduced.
