ABSTRACT:
An image forming apparatus for detecting and eliminating avoidable image reading operations includes a scanner for reading an original document, a memory for storing read image data, a printer for forming an image in accordance with the image data read from the memory, a ten-key pad for inputting instructions specifying a total number of sets of copies to be made, various functions to be performed by the apparatus for changing how the copying is performed and a sample set command by which the apparatus enters into a sample set command mode wherein one copy of the original document is output as a sample copy, and a controller for determining whether to use the image previously stored in the memory to output the rest of the total number of sets of copies to be made or performing an operation of reading the original document again depending upon types of functions input via the ten-key pad during the sample set command mode.
