摘要： An image forming apparatus includes a toner image forming portion, an information acquisition portion and a control portion. The control portion carries out processes (i) and (ii). In the process (i), the control portion causes the toner image forming portion to form, as a test image, at least either one of a toner image of single dot and a toner image of dot line consisting of single dots arranged in one or more rows in a predetermined direction, and then causes the information acquisition portion to acquire optical information on the formed test image. In the process (ii), the control portion corrects a condition for forming the toner image in the toner image forming portion, based on a state (size, concentration distribution, edge shape) of the test image obtained from the optical information acquired by the information acquisition portion.

摘要： Provided is an image forming apparatus capable of reducing power consumption by optimizing preliminary operation of a sensor. In the image forming apparatus, when tone characteristics adjustment is instructed (Step S1003: Y), tone characteristics adjustment (Step S1006) is executed after calibration (Step S1004), while when mixed-color correction is instructed (Step S1007: Y), mixed-color correction processing (Step S1009) is executed after calibration (Step S1008). Further, in the case where mixed-color correction is executed after tone characteristics adjustment, the preliminary light emission time in calibration is set shorter than when mixed-color correction is executed without performing gray adjustment first.

摘要： An image forming apparatus includes a toner image forming section, a detection section, a variation calculation section, a user setting acquisition section, an adjustment ratio calculation section, and an adjustment section. The toner image forming section forms a toner image. The detection section detects a toner density of the formed toner image. The variation calculation section obtains a variation in toner density based on the detected toner density. The user setting acquisition section acquires a user setting concerning a degree of adjusting the toner density. The user setting is set by a user. The adjustment ratio calculation section calculates an adjustment ratio which is a ratio at which the user setting is reflected, in accordance with the variation in toner density. The adjustment section adjusts the toner density based on the variation in toner density, the user setting, and the adjustment ratio.
