摘要： An image forming apparatus includes an image reading section that reads an image on paper to generate image data, and an image forming section that forms on paper an image based on image data. The image forming section forms on paper a dimension correction image including marks. The image forming section includes a computation unit that performs computation using dimension correction image data, obtained by reading the dimension correction image, to generate dimension correction data, and a memory that stores the dimension correction data. The image forming section corrects image data using the stored dimension correction data and forms an image based on the corrected image data. The computation unit has a first computation mode of generating first dimension correction data based on distances between the marks and a second computation mode of generating second dimension correction data based on distances between edges of paper and the marks.

摘要： An image forming apparatus includes a document reading section and an image forming section. The document reading section reads a document image placed on a paper placement table and generates image data. The image forming section forms an image on a sheet of paper on the basis of the image data, and includes a memory that stores test data representing a test image, which is to be formed on a sheet of paper having a size larger than the size of the table, a correction-amount calculation unit that calculates correction amounts on the basis of image data representing the test image which is formed on the sheet of paper and which has been read by repeating an operation, and a correction-amount memory that stores the correction amounts. The image forming section forms, on a sheet of paper, an image corrected on the basis of the correction amounts.
