摘要： An image forming apparatus includes a latent image forming unit in which a light beam scans in a second scan region wider than a first scan region. The light beam is modulated in accordance with an image signal within the range of the first scan region for every scanning cycle and guided onto the effective image region to form a line latent image. A write timing adjuster adjusts a write start position for writing a latent image along the main scanning direction, based on a time difference between a first detection signal output when a first light beam scanning away from the effective image region moves passed an optical sensor, and a second detection signal output when a second light beam scanning toward the effective image region moves passed the optical sensor.

摘要： Image data is inputted from a data processing device 23 into storage means 24 formed on a light-emitting element (yellow) line head 28 so that light emitting elements in one line 28a expose pixels on an image carrier in response to output signal from a shift resistor 24a. As the image carrier is moved in the direction of X to bring said pixels to reach the position corresponding to light emitting elements in the next line 28b, the image data is transmitted to a shift resistor 24b so that the shift resistor 24b outputs the image data to light emitting elements in the line 28b, whereby the pixels are exposed to light again. The movement of the image carrier and the transmission of the image data to the respective shift resistors are sequentially conducted, thereby conducting multiple exposure of each same pixel.

摘要： An image forming method which generates a video signal corresponding to an image forming command based on a video clock signal, modulates a light beam according to the video signal, and scans the modulated light beam along a main scanning direction by means of an oscillation mirror which resonates based on a drive signal, so as to form a latent image in an effective image region of a latent image carrier, the method includes: synchronizing the drive signal with the video clock signal to synchronize a detection signal with the vide clock signal, the detection signal being output from a detector which detect the light beam scanned in the main scanning direction in a region away from an effective scan region which corresponds to the effective image region; controlling a resonant frequency of the oscillation mirror based on the detection signal so that the resonant frequency of the oscillation mirror almost coincides with the frequency of the drive signal; and adjusting a position, at which the latent image is written over the latent image carrier, is adjusted by adjusting output timing of the video signal based on the detection signal from the detector.

摘要： A light scanning apparatus makes a light beam scan along a main scanning direction on an effective scanning region which has a predetermined width. The apparatus comprises: a light source which emits the light beam; a deflector which includes an oscillation mirror which oscillates about an oscillatory axis which is orthogonal or approximately orthogonal to the main scanning direction, deflects the light beam emitted from the light source using the oscillation mirror, and makes the light beam scan a second scanning range which contains but extends beyond a first scanning range which corresponds to the effective scanning region; a detector which detects the scanning light beam which moves through a position which is outside the first scanning range but is within the second scanning range, and outputs a signal; and a controller which controls a mirror drive signal fed to the oscillation mirror based on the output signal from the detector and accordingly adjusts the amplitude of the oscillation mirror. In the apparatus above, the controller stops driving the oscillation mirror when confirming based on the output signal that the oscillation mirror is under abnormal control.

摘要： A transmission optical system comprises a concave surface mirror whose reflection surface is directed toward a deflection mirror surface and a transmission lens which is disposed between the concave surface mirror and the deflection mirror surface. A light beam deflected by a deflecting element at a first deflection angle is guided to the concave surface mirror via the transmission lens, and the light beam returned by the concave surface mirror is guided to the deflecting element via the transmission lens. In consequence, the deflecting element reflects the light beam twice, and the light beam is emitted toward a scanning lens at a second deflection angle which is larger than the first deflection angle.
