PURPOSE:To provide an image forming device which can adjust an image forming condition or the handling condition of a paper by precisely grasping temperature and relative humidity in the device and form an image with a stable density without making the device large in size and expensive. CONSTITUTION:Plural thermometers 2-1, 2-2, 2-3, 2-4 and 2-5 and a hygrometer 3 are provided at proper positions in the image forming part 1 of the image forming device. Besides, an arithmetic means 11 calculating the relative humidity of the respective parts from the information of the temperature and the information of the relative humidity obtained by the thermometer and the hygrometer and a control means 5 setting the image forming condition or the like according to the information of the relative humidity obtained by the arithmetic means 4 are provided in the device. Thus, the proper image forming condition is adjusted at any time according to the change of an environmental condition such as the temperature or the humidity and the image with the stable density is obtained. |
