Image forming system for single bit image data

摘要

An image forming apparatus and an electronic device for outputting data to the image forming apparatus. The image forming apparatus comprises an interface for inputting single bit image data and a command from an external device, a first store for storing the single bit image data, a second store for receiving and storing color data for coloring the single bit image data, and an image forming device for forming a color image on the basis of the data in the first and second stores. The electronic device includes a first output for outputting single bit image data, a second output for outputting a color number for one pixel of color image data, and a third output for outputting both first multi-level color component data for the single bit image data and second multi-level color component data for the color number.
