An image processing apparatus has an image input section, a color image processor, a monochrome image processor and an image synthesizer. The image input section inputs image data of an original image. The color image processor generates color image data by performing color image processing on the image data. The monochrome image processor generates monochrome image data by performing monochrome image processing on the image data. The image synthesizer generates synthesized image data by synthesizing the monochrome image data with the color image data. The apparatus also has a buffer that temporarily stores image data, a determination section that determines on the basis of the image data of the original image whether the original image is color or monochrome, and an output controller that controls an image output process. The output controller outputs output color or monochrome image data fetched from the buffer as determined to be appropriate.

Image processing apparatus

The inventive device reduces noises and stabilizes the image quality of an image forming apparatus by reducing vibration thereof by reducing vibration of a driving source itself within a preset frequency range without changing the resonating condition of a housing. A mass member is added to a stationary shaft of a driving motor for rotating a polygon mirror. It then becomes possible to reduce the vibration and noise of an image forming apparatus by avoiding resonation by moving a resonance point by adding the mass member to the stationary shaft. Thus, a high image quality image forming apparatus can be realized.
