ABSTRACT:
An image forming apparatus comprises a writing circuit that writes the image data read by a scanner into an image memory, a coding circuit that reads and codes the image data stored in the image memory and stores the coded data in a code memory, a decoding circuit that decodes the coded data stored in the code memory and writes the decoded data into the image memory, and a printer that forms an image using the decoded image data in the image memory. The writing of the scanner image data into the image memory and the coding of the image data in the image memory or the decoding of the image data in the image memory and the printing of the decoded data in the image memory are advanced simultaneously, improving the processing speed.
