摘要： An image forming apparatus includes a housing, a drum, a toner processing module and a first mounting space. The drum is disposed in the housing. The toner processing module supplies toners to the drum. The first mounting space accommodates a first print head. The first print head provides a light ray to perform a writing operation on the drum. When the first print head is present, the light ray of the first print head disposed in the first mounting space passes through an optical channel of the toner processing module to perform the writing operation on the drum. Thus, the optimum configurations of the print head and the drum can be achieved, to effectively reduce a size of the image forming apparatus and satisfy diversified requirements without spending a high cost.

摘要： An image forming apparatus, having a photosensitive drum assembly, an exposure head, and a bearing, is provided. The photosensitive drum assembly includes a photosensitive drum and a flange disposed at an end of the photosensitive drum in an axial direction of an axis of the photosensitive drum. The flange contacts an inner surface of the photosensitive drum. The exposure head includes a plurality of light emitters aligned along the axial direction of the photosensitive drum, a lens array focusing light from the light emitters on the photosensitive drum, and a head frame to support the light emitters and the lens array. The bearing has a first contact face to contact the exposure head to define a distance between the lens array and the photosensitive drum along a direction of an optical axis of the light.

摘要： An image forming apparatus includes a rotatable image bearer, an exposure device, a development unit, an adjuster, and a magnetic member. The exposure device forms a latent image on a surface of the image bearer. The developing unit renders the latent image visible with developer including toner and carrier. The adjuster contacts each of the image bearer and the exposure device to regulate a distance between the image bearer and the exposure device. The magnetic member is arranged side by side with the adjuster in a direction of rotation of the image bearer.

摘要： A light beam scanning device deflecting, by using a rotating polygon mirror, a light beam emitted from a light source and condensing, by using a scanning lens, the deflected light beam onto a scanned surface. The light beam scanning device includes: a base made of a metal or a resin; a motor unit attached to the base and rotating the polygon mirror; a holding member holding the scanning lens; and one or more fixing members disposed between the base and the holding member, fixing the holding member to the base with the scanning lens spaced away from the base. In the light beam scanning device, the base has, between at least one of the fixing members and the motor unit, a penetrating hole or groove around which heat transmitted from the motor unit through the base to the fixing member passes.

摘要： An image processing apparatus includes a beam corrector which corrects a gray level of each pixel in image data so as to reduce a density difference due to a misalignment in beam position of laser beams of a multibeam array. The beam corrector includes a calculator which detects an edge of an object between a pixel and adjacent pixels of the pixel in the image data and calculates an edge intensity of the edge. The calculator calculates a corrected gray level of the pixel from the calculated edge intensity and a correction value corresponding to a deviation in beam position of the laser beams emitted according to a gray level of the pixel.
