Even in a digital copying machine or facsimile that outputs an image signal read by an image scanner by a printer, the time from the start of reading a document to the end of print output is at most several tens of seconds.

On the other hand, when printing an image created by a computer or a word processor, the image information is converted into a signal by a process different from that of the image display device, and this signal is sent to a print output device such as a printer for print output. It is usual for the device to convert this again into image information and output it as a printed matter. Therefore, it takes time to perform communication processing and conversion processing during that time,
Depending on the content of the image information, it may take several tens of seconds to several minutes, or even tens of minutes in some cases to obtain a print. That is, in a computer or the like, there is a problem that the print output takes the longest time in a series of processing operations.

The present invention has been made in view of such a situation as described above, and regardless of the means for obtaining an image signal,
It is an object of the present invention to provide an image forming apparatus capable of shortening the processing time by converting all into an optical reading method.
