    摘要: An image forming apparatus capable of enhancing the accuracy of the scanning position of a laser beam to thereby obtain a more precise image. Optical sensors detect reflected light from a surface of a photosensitive drum. During image formation, the apparatus detects the scanning speed of the laser beam in a main scanning direction based on detection signals from the respective optical sensors in each of divisional sections of an image forming area in the main scanning direction. The apparatus corrects magnification of the image in the main scanning direction, based on results of detection of the scanning speed of the laser beam in the main scanning direction.

    摘要: An optical scanning apparatus capable of properly correcting a main scanning scale factor. Upstream and downstream laser-light detection sensors of the optical scanning apparatus each generate a signal when first or second light beam passes through each of slits formed in the sensors. Based on signals, a scanning time required for each light beam to scan between the sensors is measured. A correction coefficient is decided by a correction value calculation unit based on a difference between wavelengths of the first and second light beams, a scanning time difference is calculated by a comparison unit based on the correction coefficient and scanning times of the light beams, and the downstream laser-light detection sensor is rotated by a sensor rotation drive unit to make the scanning time difference zero, whereby the slits are made parallel to each other.
