摘要： The present invention provides an image forming apparatus that adjusts the amount of light of a light-emitting unit with high accuracy and suppresses an increase in control time that is required to adjust the amount of light, a scanning optical apparatus, and control methods thereof. To accomplish this, the image forming apparatus of the present invention derives a threshold current and a bias current of the light-emitting unit. Further, the image forming apparatus of the present invention supplies the bias current to the light-emitting unit when causing the light-emitting unit to emit light in an amount of light corresponding to the minimum density level, and supplies a current that is larger than the threshold current to the light-emitting unit when causing the light-emitting unit to emit light in an amount of light corresponding to a density level that is larger than that minimum density level.

摘要： An optical scanning apparatus forms a latent image by scanning a laser beam emitted from a light source on an image bearing member. The apparatus includes first and second laser beam detectors for detecting the laser beam and a scanning-line slope detector for detecting a slope of a scanning line on the image bearing member on the basis of the result of detection obtained by the first and second laser beam detectors. The first laser beam detector detects the laser beam in a scanning area in front of an area in which the latent image is formed on the image bearing member and the second laser beam detector detects the laser beam in a scanning area behind the area in which the latent image is formed on the image bearing member.
