    摘要: An image can be outputted with a high sharpness without deteriorating a resolution. In order to output an image of a high picture quality while suppressing the occurrence of a moire, an exposure amount is modulated in accordance with pixel density information of the image divided into pixels of a predetermined size by an exposure amount modulating unit in a light scanning unit, thereby expressing an image dark/light state. In this case, in a highlight density region in which a pixel density is equal to or less than ⅓ of the maximum image density, the density data of two adjoining pixels is modulated by one pixel and the other pixel is not recorded. In a density region in which the image density lies within a range from ⅓ to ½ of the maximum image density, a part of the density data of one of the two adjoining pixels is transposed to the other pixel. In a density region in which the image density is equal to or larger than ½ of the maximum density, the pixel transposition is not performed.

    摘要: An image forming apparatus includes a movable photosensitive member, a slit for imagewise exposure of said photosensitive member to light in a slit exposure area having a width in a direction of movement of said photosensitive member, and a movable reflecting member for forming a non-image area on said photosensitive member by light from said reflecting member. When blank exposure is effected, the reflecting member is disposed at a first position or a second position. When the reflecting member is disposed at the first position, the light from the reflecting member is substantially condensed on or adjacent to an upstream end of the exposure area width on the photosensitive member with respect to the movement direction of the photosensitive member, and an area before an image area on the photosensitive member in which an image is formed by the slit exposure means is exposed to the light. When the reflecting member is disposed at the second position, the light from the reflecting member is substantially condensed on or adjacent a downstream end of the exposure area width on the photosensitive member, with respect to the movement direction of the photosensitive member, and an area after the image area is exposed to the light.

    摘要: An illumination optical system which can use light from a light source with high efficiency and can provide an illumination luminous flux with highly uniform illuminance, is disclosed. The illumination optical system illuminates an illumination surface with a generally telecentric illumination luminous flux. In light intensity distribution of illumination light on the illumination surface changing depending on a deviation angle of an incident ray with respect to a normal to the illumination surface, the illumination optical system operates the illumination luminous flux such that a ratio of angle widths at which light intensity reaches half of a peak value in each of two axis directions orthogonal to each other on the illumination surface is an aspect ratio of 2:1.

    摘要: A method for manufacturing an ink jet head. In a thick film laminating step, a patterning layer corresponding to the configuration of ink flow paths on a member provided with a pressure generating source is formed, and an inorganic material layer is overcoated on the patterning layer to form an ink discharge surface. A patterned image of a predetermined ink discharge port configuration is irradiated by a laser capable of completing a sublimate ablation process before the laser beams are dispersed in a work piece as thermal energy. Subsequently, the sublimate ablation process is executed on ink discharge ports almost simultaneously from the inorganic material layer on the ink discharge side up to the interior of the thickness of the patterning layer. The patterning layer is removed after processing the ink discharge ports.

    摘要: A method for forming through holes, which has laser beam as the light source to project the laser beam to the work object using an optical system through a photomask for the formation of through holes on the work object by ablation processing, comprises the steps of increasing the concentration of the optical processing energy contributing to the process using the reflected beam created from the work object in the laser ablation processing; and forming each of through holes having the configuration enabling the narrower end to be changed to the wider end in the incident direction of laser beam. With the structure thus arranged, it becomes possible to increase the energy concentration that contributes to the process as compared with the usual ablation processing, because the reflected beam created in the ablation processing can be utilized again for the optical processing. Then, each of the through holes can be formed easily in the configuration in which the narrower end changes to the wider end in the incident direction of laser beam, which cannot be easily processed by the application of the usual ablation processing.
