摘要： A noise masking system in an image forming apparatus such as a laser beam printer or a copying machine having a drive mechanism acting as a noise generation source during operation, the noise masking system comprising a masking sound generator for generating a sound to mask the noise and masking sound control device which controls the masking sound generator to generate a masking sound of a frequency range including a main-component frequency of the noise. The masking sound thus generated is of a frequency range from a lower-limit frequency to an upper-limit frequency in a critical band of the main-component frequency of the noise. The noise masking system masks noise without decreasing the sound pressure of the noise.

摘要： An image processing device includes a generating unit and an output unit. The generating unit generates image data on the basis of which an image forming unit forms a visible image on a recording medium containing detectable substances using only a coloring material having a spectral reflection factor that is different in a particular wavelength range from a spectral reflection factor that the detectable substances have by a predetermined threshold or more. The output unit outputs the image data generated by the generating unit to the image forming unit.
