<p>An image forming method in which digital image data are stored in a memory and are read out of the memory to form images on copy sheets in a first image orientation or in a second image orientation rotated through 180 DEG with respect to the first image orientation. First image data relating to images to be formed in the first orientation are stored in the memory in ascending address sequence, starting from the first free memory address. Second image data relating to images to be formed in the second orientation, however, are stored in the memory in descending address sequence, starting from the last free memory address, while reading out from the memory is effected in ascending address sequence for both the first and the second image data. The available memory space is thus used without any capacity loss and hence extremely efficiently, because both the first and the second image data are stored in contiguous relationship and hence the memory space still available remains contiguous.</p> |
