Image forming apparatus having a scanner

摘要

An image forming apparatus includes an original document table for supporting an original document, an optical scanning device for scanning the original document supported by the original document table to capture an image of the original document and converting the captured image to an image data, an image forming unit for forming images on an image bearing medium according to the image data obtained by the optical scanning device, and a transmitter for transmitting a timing signal from the optical scanning device to the image forming unit. The timing signal represents a period of time required from the commencement of operation of the optical scanning device to the commencement of outputting the image data from the optical scanning device. The apparatus further includes a controller for controlling the formation of the images by synchronizing the operation of the image forming unit with the operation of the optical scanning device in response to the timing signal transmitted by the transmitter.
