    Abstract: An image forming apparatus includes first to third adjustment processing portions. The first adjustment processing portion adjusts an emission light amount of a light-emitting portion of a first sensor based on an electric signal output from a light-receiving portion of the first sensor and corresponding to regular reflection light reflected by a non-toner-adhering surface of an image-carrying member. The second adjustment processing portion adjusts an operation condition of an image forming portion based on a toner concentration of a first toner image in a specific color, that has a concentration smaller than a predetermined saturation concentration. The third adjustment processing portion adjusts an emission light amount of a light-emitting portion of a second sensor based on an electric signal output from a light-receiving portion of the second sensor and corresponding to diffuse reflection light reflected by a second toner image in the specific color, that has a predetermined reference concentration.

    Abstract: A processor derives a plurality of unit density values which are each an average value of sensed densities for each of a plurality of unit areas sectioned for each unit length in a test toner image. The processor derives a weighted average of the plurality of unit density values to derive a test image density used for adjusting a control parameter in a printing portion. The unit length is a greatest common factor of two target lengths corresponding to perimeters of two types of target rotating members out of the plurality of rotating members. When a number of the plurality of unit areas is represented by n, n is a value obtained by subtracting 1 from an added value of a first constant and a second constant. The first constant and the second constant are values obtained by respectively dividing the two target lengths by the unit length.

    Abstract: An image forming apparatus includes an image forming section, a controller, and storage. The storage stores therein a coverage rate of a past image specified by a past print job. The controller includes a determining section and a first calculating section. When a new print job is received, the determining section determines whether or not to perform a running-in operation by comparing a coverage rate of a new image specified by the new print job to the coverage rate of the past image stored in the storage. The first calculating section calculates an amount of toner to be supplied from a developing section to a photosensitive drum based on the coverage rate of the new image. The running-in operation is to supply the toner in the amount calculated by the first calculating section from the developing section to the photosensitive drum before the new image is formed on a sheet.

    Abstract: An image forming apparatus is provided to correct color misregistration and includes an image correcting unit. A toner density adjustment patch image forming section forms toner density adjustment patch images, and a toner density adjustment patch image misalignment measuring section measures amounts of misalignment of the images. Then, a color-misregistration correction patch image forming section forms color-misregistration correction patch images on a transfer member. A color-misregistration correcting section measures amounts of misalignment of the color-misregistration correction patch images to correct the color misregistration. The control unit controls the color-misregistration correction patch image forming section to change color-misregistration correction patch images to be formed in accordance with the amounts of misalignment of the toner density adjustment patch images measured by the toner density adjustment patch image misalignment measuring section.
