An image processing system with a buffer memory for use in a facsimile device. An image processing apparatus comprising an image read unit for operating continuously to read an image on an original document, a buffer memory for temporarily storing image data of the image on the original that is read by the image read unit, a compressing unit for compressing the image data stored in the buffer memory into code data, and a buffer memory controller for controlling the operation of writing the image data into the buffer memory and the operation of reading the image data from the buffer memory. The image data processing device with buffer memory, which can continuously operate an image input terminal and/or an image output terminal, using a buffer memory which has a less number of the memory elements than a page memory.
