Abstract: An image adjustment method for an image forming apparatus in which an adjustment image is formed by transferring a plurality of reference images formed by a color component to be the reference among a plurality of color components and a plurality of images to be adjusted, which are formed by other color component to be adjusted, onto a transfer medium so that the images to be adjusted are superposed on the reference images, the density of the formed adjustment image is detected, and an image forming position of the other color component to be adjusted is adjusted based on the detected density of the adjustment image.

Abstract: An average concentration value is detected within a measurement area (about 10 dots) corresponding to the pitch of a detection pattern in the total color matching adjustment range (100 dots), and from a value detected as a local maximum value, a candidate for correction value for the exposure timing of an adjustment image is acquired within the color matching adjustment range. This process is carried out for two types of detection patterns having different pitches thereby to acquire two candidates. A correction value for the exposure timing is determined from a candidate shared by the two detection patterns. At the time of color matching adjustment, the wasteful consumption of the developer or the like is suppressed, while carrying out the color matching adjustment efficiently within a short time.

Abstract: In the present applying mechanism, a part of a guide sheet 33 bulges (arches) away from an oil application roller 16, with respect to a vertical line S passing through the center of a pipe 31. In other words, in the present applying mechanism, a part of the guide sheet 33 has a shape of avoiding (bypassing) the oil application roller 16 that has a high temperature. With this, oil flowing on the guide sheet 33 is kept away from the high-temperature oil application roller 16. On this account, it is possible to restrain the degradation of the oil flowing on the guide sheet 33 on account of the heat from the application roller.
