PURPOSE:To obtain a distinct copied image even under any environment and atmosphere such as high humidity, low temperature and high temperature by providing a temperature and/or humidity detection means and a heating means. CONSTITUTION:A main charger 2, an exposing means 3, a developing device 4, a transfer charger 5, a separation charger 6, a separation pawl 7, post-transfer conveyance part 8, a cleaner 9 and a destaticizing lamp 10 are arranged on the periphery of a organic photosensitive body 1. A cassette 12 where a transfer paper 11 is housed is arranged below the photosensitive body 1, and a heater 13 and the temperature and/or humidity sensor 14 are provided between the photosensitive body 1 and the cassette 12. In a copying process, the temperature and/or humidity sensor 14 provided between the photosensitive body 1 and the cassette 12 detects the temperature and/or humidity of the atmosphere and transmits an action signal to the heater 13 in accordance with the detected value so as to make the heating means act to eliminate the moisture of a transfer material or a photosensitive body. Thus, the distinct image is obtained under every kind of environment. |
