摘要:
A recording material recognizing device which enables a detection determining whether or not the recording material has passed and a detection determining the width of the recording material to be performed at one time, and also enables a detection determining a thickness, a resistance and a dielectric constant, of the recording material to be performed when physical values of the recording material are also required for stabilizing an image quality.
