摘要： An optical scanning device includes a light source, a photodetector, an optical element group, and a polygon mirror. The light source is configured to emit laser light. The photodetector is configured to detect a beam formed with the laser light. The optical element group is configured to guide the beam to the photodetector. The polygon mirror is configured to perform deflection scanning on the beam, which deflects the beam from a first end in one direction of a main scanning direction to a second end on a side opposite to the first end of the main scanning direction. The beam is incident on the same side of the photodetector when the beam is deflected toward the first end and the second end by the polygon mirror.

摘要： An optical scanning device includes a first light source, a second light source, a first aperture, a second aperture, a third aperture, and a deflector. The first light source emits a first light flux. The second light source emits a second light flux. The second light flux is separated from the first light flux by an opening angle in a main scanning direction. The first aperture shapes a beam shape of the first light flux in a sub-scanning direction. The second aperture shapes a beam shape of the second light flux in the sub-scanning direction. The third aperture shapes the beam shape of the first light flux and the beam shape of the second light flux. The deflector deflects the first light flux and the second light flux at positions separated in the sub-scanning direction on a surface.

摘要： A pressure adjusting device includes a housing with a cylinder. A piston moves within the cylinder in an axial direction. A pulse motor is fixed to the housing. A switch provided on a surface of the cylinder is actuated by movement of the piston in the cylinder in the axial direction. The switch includes a fixed contact point and a moveable contact point. The piston presses the movable contact point to abut against the fixed contact point when the piston moves from a position other than the initial position to the initial position so that the movable contact point electrically contacts the fixed contact point.

摘要： An optical scanning device includes plural sets of optical paths, and in each set of optical paths, first and second light beams emitted from the two light sources having an opening angle in the main scanning direction are orthogonal to a deflection axis of a deflector and are deflected and scanned by the same surface of the deflector at different positions deviating from each other in a deflection axis direction. A first imaging optical element gives positive optical power to the deflected light beams to converge the light beams. A focal position exists between the first imaging optical element and a second imaging optical element arranged on the optical paths in front of first and second surfaces to be scanned on two photoconductive drums. A separation distance exists between the light beams.
