Abstract: An image forming apparatus has a light scanning apparatus which is capable of aligning a lens with a plurality of light-emitting devices and forming a high-quality image while suppressing generation of moiré. In a first image formation mode, light-emitting devices outputting light beams exposing both ends of the photosensitive member in a rotational direction and at least a part of light-emitting devices exposing an area between exposure positions of the light-emitting devices outputting the light beams exposing the both ends are used to form an electrostatic latent image on the photosensitive member. In a second image formation mode, the light-emitting devices outputting the light beams exposing both ends are not used, and at least a part of light-emitting devices exposing an area between exposure positions of the light-emitting devices outputting the light beams exposing both ends are used to form the electrostatic latent image on the photosensitive member.

Abstract: A saddle riding type vehicle includes a stabilizer arranged to support a pair of wheels arranged at opposite sides of a vehicle body to be movable up and down relative to the vehicle body, and a switching mechanism arranged to switch between a movable state in which the pair of wheels are permitted to move up and down and a locked state in which the pair of wheels are restricted from moving up and down. The switching mechanism includes a coupling pin member arranged to engage with the stabilizer to set the stabilizer to the locked state thereby restricting rotation of the stabilizer relative to the vehicle body, and to disengage from the stabilizer to set the stabilizer to the movable state thereby permitting rotation of the stabilizer relative to the vehicle body, and a solenoid fixed to the vehicle body and arranged to drive the coupling pin member into and out of engagement with the stabilizer.

Abstract: Density unevenness is suppressed even in an image that is formed by a multiple exposures method in which the same region on a photoreceptor is exposed multiple times with different laser light sources (light emitting elements), by adjusting the amounts of light of the respective lasers based on a density difference among test images. An image is formed for each group of light emitting elements grouped together for multiple exposures by dividing, in the main scanning direction, the region of a test image formed on a recording medium. The images formed for the respective multiple-exposure light emitting element groups are compared to one another in density, to thereby adjust the amounts of light of the respective laser light sources (light emitting elements) and reduce fluctuations in image density.

Abstract: A storage stores data of charging electric potentials at two or more points on a surface of an image carrier, and coordinates thereof expressed using a main-scanning position and a sub-scanning position thereof. A determination unit determines a correction value of a light power from the data of charging electric potentials at two or more points and coordinates thereof that have been read out from the storage unit. The correction value is applied to the light source so as to reduce the charging electric potential or the charging electric potential unevenness of coordinates on the surface of the image carrier. A correction unit uses the determined charging electric potential or correction value to correct the light power of the light source so as to mitigate an influence of charging unevenness at each set of coordinates.

Abstract: A first mark and a second mark are provided on a photosensitive drum and a rotation reference position sensor detects these marks. A counter is reset according to a detection signal corresponding to the first mark, and is incremented its count value according to a detection signal corresponding to the second mark. A CPU controls an exposure intensity based on light amount correction data read from a memory according to the counted value.

Abstract: A saddle riding type vehicle includes a balancer beam rotatably mounted on a vehicle body to cause a right wheel and a left wheel to move up and down in opposite directions, and is capable of making turns by leaning the vehicle body. The saddle riding type vehicle also includes a headlight, a drive mechanism arranged to rotate the headlight, a front detector arranged to detect a rotation angle of the balancer beam relative to the vehicle body, and a controller programmed to control the drive mechanism based on a result of detection by the front detector. The rotation angle detected by the front detector corresponds to an angle of the vehicle body leaning sideways relative to a traveling surface (relative lean angle). The controller controls the drive mechanism based on such result of detection by the front detector. The headlight can therefore illuminate directions of movement properly.
