An image reading and processing apparatus scans an image-carrying medium along a predetermined path and, during each cycle of line scanning, image data is produced from a line of pixels and is stored into image data memories while data-write and date-read address signals are generated by first and second address generators and are supplied independently of each other to the image data memories. A second address generator is operative to supply data-read address signals to the image data memories at a timing regulated on the basis of a signal indicative of a magnification/reduction ratio at which an image on an image-carrying medium is to be reproduced. An attribute data storage memory has a plurality of memory spaces respectively corresponding to a plurality of scanning areas, each memory space storing attribute data designating the conditions in which the image is to be reproduced. The attribute data storage memory is responsive to an attribute data address signal for outputting the attribute data corresponding to the attribute data address signals, wherein the image data output from the image data memory is processed on the basis of the attribute data output from the attribute data storage memory in all magnification/reduction ratios.
