Abstract:
An electrophotographic image forming apparatus for transferring image information and forming an image on a medium while producing electromagnetic interference below a desired level, the apparatus comprising:an image processor for receiving a high-frequency image information signal containing the image information and having a high frequency, the image processor further for forming a plurality of low-frequency image information signals based upon the high-frequency image information signal, each low-frequency image information signal having a low frequency which is substantially less than the high frequency;a low-frequency interface connected to the image processor for transferring the low-frequency image information signals while producing electromagnetic interference below the desired level;a control circuit connected to the low-frequency interface for receiving the low-frequency image information signals from the low-frequency interface, and for combining the low-frequency image information signals to form at least one reconstructed high-frequency image information signal therefrom, the reconstructed high-frequency image information signal having substantially the same high frequency and containing the same image information as the high-frequency image information signal received by the image processor;a high-frequency interface connected to the control circuit for transferring the reconstructed high-frequency image information signal while producing electromagnetic interference below the desired level; andan image formation device connected to the high-frequency interface for forming an image on the medium based on the image information contained within the reconstructed high-frequency image information signal.
