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： An image It is formed as a patch image which includes a header image portion Ih of a solid image having a length of a circumferential length of a developing roller or more, and a gradation image portion Ig progressively varied in the tone level thereof from the maximum level to the minimum level. The densities of the patch image on an intermediate transfer belt are sampled. However, the sampling results contain errors resulting from noises or variations and hence, are subjected to a noise removal process, a periodical variation correction process and a reverse correction process. The results detected on the intermediate transfer belt do not always coincide with image densities (OD values) on a recording material. Therefore, the detection results are converted into the OD values, based on which tone characteristics of an apparatus is estimated. Then a tone correction table is updated in a manner to compensate for the tone characteristics. This approach is taken to improve image quality on the recording material.

摘要： A wire bar is formed by winding a wire, which comprises a first flat portion formed along an overall longitudinal length, around a peripheral surface of a metal core such that the peripheral surface of the metal core and the first flat portion tightly contact with each other. Since this increases the area size of a contact portion where the wire and the metal core contact each other, it is possible to increase the force of static friction which fixes the wire to the metal core. Fixing of the wound wire to the metal core by the strong force of static friction effectively prevents the wound wire from getting deviated.

摘要： In an image forming apparatus including plural exposure units each deflecting a light beam from a light source by means of an oscillation mirror in resonant oscillations and scanning the deflected light beam on a latent image carrier thereby forming a latent image on the latent image carrier, every one of the exposure units assuredly attains an adequate amplitude of the oscillation mirror for ensuring the formation of images of high quality. More specifically, a CPU 101 retrieves resonant frequencies of individual deflectors previously stored in a memory. The CPU 101 calculates an average value of these resonant frequencies and applies a drive command to mirror drivers 1022 of the exposure units 6Y, 6M, 6C, 6K such as to drive all the deflectors into oscillations at the average value. Alternatively, a resonant-frequency adjusting section 653 makes adjustment to match the resonant frequencies of the individual deflectors substantially with a drive frequency. This ensures that all the oscillation mirrors attain adequate amplitudes.

摘要： As a scanning light beam which is scanning and traveling away from an effective image region moves passed the location of a sensor, a horizontal synchronizing signal Hsync is obtained as a first detection signal. A deflection mirror surface turns around, thereby reversing the direction in which the scanning light beam scans. This scanning light beam therefore scans an effective image region IR, and a latent image forming operation using this scanning light beam is controlled based on the horizontal synchronizing signal Hsync. Hence, there is a relatively long period of time (T4+T5) since the horizontal synchronizing signal Hsync is obtained until formation of a latent image starts in accordance with the signal Hsync. This secures sufficient time for control of the latent image forming operation based on the horizontal synchronizing signal Hsync, and hence, realizes the latent image forming operation as desired during the time T6.
