    摘要： There is provided an image forming apparatus which can implement digital control of a laser beam scan (analog amount) that moves at high speed, without using any high-speed, multi-bit A/D converter. Upon executing a digital process on the basis of analog detection value Vo corresponding to the passage position or light beam power of a light beam with which a photosensitive drum is irradiated, comparator CMP0, comparison reference value (threshold value) Vr of which changes in correspondence with detection value (integration output) Vo, is used. New comparison reference value Vr is supplied to comparator CMP0 on the basis of digital data BMDA corresponding to output CMPOUT of this comparator.

    摘要： A light beam is made to scan and expose a photosensitive drum in the main scanning direction and the passing position of the light beam in the sub-scanning direction is sensed. On the basis of the result of the sensing, the light beam is shifted in the sub-scanning direction when the beam is made to scan by a scanner so that the passing position may come in a target range, which brings the passing position to the proper position. After the position control, the passing position of the light beam is confirmed and controlled so that the passing position may fall on the proper position a specific number of times consecutively. When the light beam is shifted in the sub-scanning direction, the passing position of the light beam is brought into a final target range in such a manner that the target range is forced to converge stepwise in a first range and then in a second range narrower than the first range.

    摘要： An image forming apparatus including a plurality of latent image forming units for forming latent images on a plurality of image carriers, a plurality of developing devices for forming developed images by developing the latent images formed by the latent image forming units, and an image conveyer belt for conveying the developed images formed by the developing devices. The image forming apparatus further contains a registration sensor for detecting the developed images conveyed on the image conveyer belt, and the registration sensor has a light source, a first optical fiber element for guiding the light from the light source and illuminating the image conveyer belt to obtain the reflected light, a second optical fiber element for guiding the reflected light in a specified direction, and a light receiving element for converting the reflected light guided by the second optical fiber element into an electric signal. The image forming apparatus has a computing device for a computing misregistration correcting amount to correct the misregistration of each of the developed images conveyed by the image conveyer belt based on the detecting result of the registration sensor and executes the correction of the misregistration based on the computed result of the computing device.
