An image forming device is disclosed which can positively conserve expensive consumable products such as toner and ink or the like and which can provide copied material which conforms to the intent of the user by using a simple operation. The image forming device includes an original document attribute detection unit that detects whether an original document to be copied is color or monochrome, an automatic mode switching unit that automatically switches between a color mode which forms a color image and a monochrome mode which forms a monochrome image based on the original document attribute detected by the original document attribute detection unit, and an image forming unit which copies an original document image to recording paper using the mode switched to by the automatic mode switching unit, and provides a priority mode switching unit which gives priority to switching by the automatic mode switching unit and forcibly switches to the monochrome mode.
