The CPU selects one of the plurality of adjustment conditions, adjusts the position at which the image is to be formed based on the selected adjustment condition, and causes the printer controller to form the image on the sheet. ## Claims ### Claim 1 An image forming apparatus, comprising: an image forming unit configured to form an image on a sheet; and a controller configured to: cause the image forming unit to form a test image on the sheet; obtain read data, which is obtained by reading the test image formed on the sheet; and control a predetermined image formation area, in which the image forming unit is able to form an image, based on the read data, the controller being configured to perform a first adjustment process of adjusting the predetermined image formation area to a first area and a second adjustment process of adjusting the predetermined image formation area to a second area, the first area having a rectangular shape, the second area having a shape similar to a shape of the sheet having the test image formed thereon. ### Claim 2 (depends on 1) The image forming apparatus according to claim 1, further comprising a receiver configured to receive user instruction information, wherein the controller is configured to select an adjustment process from among a plurality of adjustment processes including the first adjustment process and the second adjustment process, based on the user instruction information. ### Claim 3 (depends on 2) The image forming apparatus according to claim 2, wherein the controller includes an image processor configured to perform image processing, based on an image processing condition, on image data, and wherein, when one of the first adjustment process and the second adjustment process is not selected based on the user instruction information, the controller causes the image processor to perform the image processing on the image data based on another image processing condition. ### Claim 4 (depends on 2) The image forming apparatus according to claim 2, wherein the controller includes an image processor configured to perform image processing on image data, wherein, when the first adjustment process is to be performed, the controller causes the image processor to perform the image processing on the image data based on a first image processing condition, and wherein, when the second adjustment process is to be performed, the controller causes the image processor to perform the image processing on the image data based on a second image processing condition. ### Claim 5 (depends on 4) The image forming apparatus according to claim 4, further comprising: a first reader, which includes an original table, on which the sheet having the test image formed thereon is to be placed, and is configured to read the test image formed on the sheet placed on the original table; and a second reader configured to read the test image formed on the sheet conveyed to the second reader, while conveying the sheet having the test image formed thereon, wherein, when causing the first reader to read the test image, the controller generates the first image processing condition, and wherein, when causing the second reader to read the test image, the controller generates the second image processing condition. ### Claim 6 (depends on 4) The image forming apparatus according to claim 4, further comprising: a storage unit configured to store a plurality of image processing conditions; and a notifier configured to notify, when the first image processing condition is not stored in the storage unit, that the first image processing condition is not stored, and to notify, when the second image processing condition is not stored in the storage unit, that the second image processing condition is not stored. ### Claim 7 (depends on 3) The image forming apparatus according to claims 3, further comprising: a storage unit configured to store a plurality of image processing conditions; and a notifier configured to notify, when an image processing condition corresponding to the selected adjustment process is not stored in the storage unit, that the selected adjustment process is not to be performed. ### Claim 8 (depends on 5) The image forming apparatus according to claim 5, further comprising: a storage unit configured to store a plurality of image processing conditions; and a display, wherein, when an image processing condition corresponding to the selected adjustment process is not stored in the storage unit, the controller displays on the display a screen for selecting whether the image processing condition corresponding to the selected adjustment process is to be generated. ### Claim 9 (depends on 8) The image forming apparatus according to claim 8, wherein, after the screen for selecting whether the image processing condition corresponding to the selected adjustment process is to be generated is displayed on the display, when a user instruction to generate the image processing condition corresponding to the selected adjustment process is input to the controller, the controller causes the image forming unit to form the test image on the sheet. ### Claim 10 (depends on 5) The image forming apparatus according to claim 5, further comprising: a storage unit configured to store a plurality of image processing conditions; and a display, wherein, when an image processing condition corresponding to the selected adjustment process is not stored in the storage unit, the controller displays on the display a screen for selecting whether an adjustment process different from the selected adjustment process is to be performed.
