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： When a gradation test pattern is read a predetermined period of time after the gradation test pattern was fixed, the correction amount can be controlled based on a stable image density, and an image with good gradation characteristics can be formed. A gradation test pattern including all color patterns is output in accordance with a gradation test pattern registered in a test pattern memory area, and at the same time, a timer is started. After an elapse of a predetermined period of time stored in a RAM, the output gradation test pattern is read by an original reader. On the basis of the read image density, a .gamma.-LUT is set.

摘要： An object of the present invention is the forming over a long period of time of images that have a desirable density and gradation.According to the present invention, an image pattern, at the maximum image density, is formed on a photosensitive drum and read by a detection unit that incorporates an LED and a photosensor. Based on the read-out data, an image forming condition is corrected so that a maximum density is slightly higher than a target maximum density. Further, an image pattern that shows density gradations is formed on the photosensitive drum, and is read by the detection unit. Based on the read-out data, the image forming condition is corrected so that the gradation characteristic is stable. With these corrections, even if the density characteristic and the gradation characteristic of the photosensitive drum are changed, the initial preferable state of the output density range can be maintained, and stable gradation characteristics for print effects that range from highlighting to shadowing is constantly ensured.
