Abstract
A facsimile apparatus in which the pixel density of image data being received or transmitted can be converted when the image being received or to be transmitted is formed. The apparatus photoelectrically reads a document image at a fixed pixel density and can be manually instructed to execute or not to execute a conversion process on the pixel density of the read image data. If instructed to execute the conversion process the image data whose pixel density has been converted is encoded and transmitted, and if instructed not to execute the conversion process the non-converted image data is transmitted.
