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.

摘要： An image forming apparatus improved in the accuracy of detecting a time period over which a laser beam is scanned. A laser beam emitted from a laser light source is deflected by a polygon mirror such that the laser beam scans a photosensitive drum. The deflected laser beam is guided onto the photosensitive drum via an imaging lens. A mode hop detection unit detects a mode hop of the laser beam. An image pulse generation section detects a main scanning magnification of an electrostatic latent image formed on the photosensitive drum. When a mode hop is detected, the main scanning magnification in a next scanning cycle is corrected using a correction value stored in a storage unit and used most lately, whereas when no wavelength variation has not detected, the main scanning magnification in the next scanning cycle is corrected using the latest correction value.

摘要： A print head having high printing reliability, in which temperature unevenness is suppressed even when printing is performed using a print head having an increased length and density of an ejection opening array can be provided. Specifically, a temperature equalizing member such as a heat pipe and a cooling liquid passage is disposed between a first support substrate and each of second support substrates or is disposed inside the first support substrate. This makes it possible to equalize temperature among the plurality of second support substrates and further equalize temperature among the printing element substrates bonded to these support substrates. In addition, the temperature equalizing member is made close to the printing element substrate, thus making it possible to efficiently equalize temperature.
