Abstract:
An image forming apparatus system, comprising:an image data transmitter transmitting image data and including a multiple value image data bus transmitting multiple value image data and a binary value image data bus transmitting binary value image data;an image data receiver receiving the image data transmitted by said image data transmitter;a clock line transmitting a clock signal in synchronism with the multiple value image data,wherein said image data transmitter and said image data receiver are connected to each other through said multiple value image data bus, said binary image data bus, and said clock line, andwherein said image data transmitter includes:an image data bus selector selecting said multiple value image data bus at a time of transmitting the multiple value image data and selecting said binary value image data bus at a time of transmitting the binary value image data; anda synchronization clock changing over circuit setting the clock signal to a transmitting state at the time of transmitting the multiple value image data and setting the clock signal to a transmission-stopping state at the time of transmitting the binary value image data.
