A method of controlling an optical output of a laser light source which scans a photosensitive body comprises the steps of detecting an optical output of the laser light source and generating a monitor signal which has a logic level indicative of whether a laser power of the optical output is greater than or less than a predetermined value, generating signals including a gate signal indicative of a scan time in which the photosensitive body is scanned based on a synchronization detection signal indicative of each scanning line, a laser diode signal having logic levels for turning the laser light source ON and OFF and an enable signal based on the monitor signal, the gate signal and a power set start signal indicative of a start of a power set operation in which the laser power is controlled to the predetermined value, and adjusting a driving current supplied to the laser light source based on the monitor signal when enabled by a certain logic level of the enable signal so as to control the laser power to the determined value.
摘要:
An optical scanner includes a light source modulated based on image data, an optical deflection and scanning part deflecting a light beam emitted from the light source, and a scanning and imaging optical system condensing the deflected light beam toward a scanning surface so as to form a light spot optically scanning the scanning surface. The effective scanning region of the scanning surface is divided into a plurality of regions according to a scanning line curving characteristic. Suitable image data for optically scanning the divided regions are selected from image data of a plurality of image lines every time the light spot optically scans the effective scanning region, so that the image data of each of the image lines is written with scanning line curving being corrected.
摘要:
An image forming apparatus including a plurality of image forming cartridges removably mounted to an apparatus body one above the other is disclosed. Structural members each partition off a space between nearby image forming cartridges mounted to the apparatus body. The apparatus is capable of obviating banding ascribable to the vibration of the cartridges.
摘要:
An optical scanner is capable of effectively correcting a difference with respect to the sub-scanning direction between the positions of optical spots for scanning photoconductor drums of a tandem type color image forming apparatus. The optical scanner includes an optical axis adjusting part. The optical axis adjusting part uses a deflecting mirror or a wedge-shaped prism to deflect the optical axis of an optical beam with respect to the sub-scanning direction. As a result, it is possible to accurately correct a resist difference among individual image forming stations and form a high-quality color image without any color displacement.
摘要:
An image forming apparatus includes a plurality of image forming cartridges removably mounted to an apparatus body one above the other and a transfer belt support unit hingedly attached to the image forming apparatus that is movable between a first position covering the plurality of image forming cartridges and a second position uncovering the plurality of image forming cartridges. Each image forming cartridge can be mounted to or dismounted from the image forming apparatus when the transfer belt support unit is in the second position. At least one of the image forming cartridges can be mounted to or dismounted from the image forming apparatus in a direction other than along an axis of rotation of a photoconductive member located in an image forming member.
