摘要： A laser beam scanning optical apparatus has a focusing lens having different optical powers in the main scanning direction and the sub-scanning direction, moving means for moving the focusing lens on an optical direction, detecting means for detecting a state of convergence of the laser beam on a scanned surface, and control means for adjusting the convergence position of the laser beam by moving the focusing lens via driving said moving means based on the detection result of the detection means. In the aforementioned construction, the state of the convergence of the laser beam on a scanned surface is adjusted in the main scanning direction and the sub-scan direction by moving the focusing lens in an optical axis. The focusing lens is moved to a position of optimum convergence based on the construction of the optical system by detecting the state of convergence in the main scan direction and the sub-scan direction via a detecting means.

摘要： A laser beam scanning optical apparatus which images and scans a laser beam emitted from a laser diode on a photo-sensitive drum through a focusing lens, a polygon mirror and an f.theta. lens. An SOS photosensor detects the scanned laser beam and generates a detection signal. The laser diode is controlled to perform pulse emission a specified time after the generation of the detection signal. The pulse beam is incident to a beam detector which adopts a knife edge method, and the amount of a focal shift is detected. The focusing lens is moved along the optical axis in accordance with the detected amount of a focal shift to correct the position of the image point.

摘要： The printing head 50 includes an insulative member 52 in which pluralities of apertures 56 are formed. Doughnut-like first and second electrodes 68 and 70 are disposed around the aperture 56. Pulse voltages V1(P) and V2(P) both having a certain polarity opposite to that of the toner particles are applied to the first and second electrodes 68 and 70, energizing the toner particles 38 to afford propelling thereof. Subsequently, a voltage V2(B) having the same polarity as the charged toner particles 38 is applied to the second electrode 70, forcing radially inwardly to converge the propelling toner particles 38 in the aperture 56. This ensures that a dot and an image both having clear contour can be formed on the sheet 8.
