摘要： An image forming apparatus includes a transfer condition setting device to set a patch image transfer condition under which multiple patch images of respective component colors are transferred from an image bearer onto a recording medium conveyor. The transfer condition setting device sets a prescribed transfer condition that decreases a difference in transfer efficiency of toner between the respective component colors when the multiple patch images of respective component colors are transferred onto the recording medium conveyor below a difference in transfer efficiency of toner between the multiple component colors caused when transferred under the same transfer condition as a multicolor toner image is transferred onto a recording medium. A correcting device corrects an image forming condition to reduce an amount of misalignment caused in the multiple component colors of the multicolor toner image based on times of outputs from a patch image position sensor.

摘要： According to the embodiments of the invention, the problem to be solved is whether errors have occurred for color sensors for calibrating density and color or their corresponding reference plates. At step S103, it is determined whether the difference is larger than a predefined threshold. If so, the sensors are determined abnormal; otherwise, it is normal. At step S111, color sensors 50a, b, c, and d read the density of recording medium 11 on at least one of its coordinates, compares the readings of sensors determined abnormal with that of sensors determined normal, and determines whether the difference obtained at step S112 is within the predefined threshold. At step S114, for color sensors determined abnormal at step S103, an abnormity alarm message is displayed on a UI as shown in FIG. 8 or sent to the user via e-mail.

摘要： Dot patterns formed by two different half-tone processes of the plurality of tone processes for each color of CMYK and formed with/without the presence and absence of transparent toner overlap are created and test patches obtained by collecting the dot patterns are printed. The printed test patches are read to generate image data, and tone correction arithmetic is performed on the basis of the image data. Concentration in the case of the presence of transparent toner in a different half-tone process is predicted based on the dot patterns with the transparent toner overlap in the test patches and concentration in the case of the absence of transparent toner in a different half-tone process is predicted based on the dot patterns without the transparent toner overlap in the test patches. The tone correction arithmetic is performed based on the predicted values.
