摘要： One embodiment of an image correction method is an image correction method for correcting image forming condition(s). The image correction method includes forming, on photoreceptor(s), correction test pattern(s) having continuously varying toner gradation; wherein a single correction test pattern in which density is varied in sequence from high to low in paper transport direction(s) is formed as a result of controlling exposing unit laser power(s) while photoreceptor charging potential(s) is/are held constant, or while develop bias(es) is/are held constant, or while photoreceptor charging potential(s) is/are held constant and develop bias(es) is/are held constant. In such case, total length(s) in paper transport direction(s) of such correction test pattern(s) is/are less than or equal to circumference(s) of photoreceptor(s).

摘要： In an optical discharge apparatus used in an electrographic image forming apparatus, by forming, on a light guiding member, a diffusing reflecting face for reflecting light from an LED lamp towards a photosensitive drum, and by supplementing the amount of light by altering the height of the diffusing reflecting face to the light emitting face and the width of the diffusing reflecting face in accordance with their distance from the light source, the light intensity distribution of the irradiating light that is irradiated onto the photosensitive drum is made uniform. Furthermore, since light that leaks from the diffusing reflecting face is reflected by a reflecting film that is pasted onto an upper face in the vicinity of a rear end portion of the light guiding member, and returned to the interior of the light guiding member, the amount of light that is irradiated from the light emitting face in the vicinity of the rear end portion of the light guiding member increases, and thus it is possible to further increase the uniformity of the light intensity distribution of the irradiating light. Furthermore, an optical discharge apparatus used in an electrographic image forming apparatus is provided with a light guiding member that is arranged facing the photosensitive drum of the image forming apparatus, and an LED lamp for irradiating the light onto the light incident face of the light guiding member. A diffusing reflecting face for reflecting the light from the LED lamp toward the photosensitive drum is formed on the light guiding member. The rear end face of the light guiding member is an optically transparent face, and the amount of irradiating light that is irradiated onto the photosensitive drum from the vicinity of the rear end portion of the light guiding member increases by forming a reflecting face behind the rear end face of the light guiding member.
