PURPOSE:To prevent the occurrence of jamming at a separating part for an image forming device, and also, to obtain a transferred image of high image quality without causing uneven transfer and defective separation. CONSTITUTION:In a housing 1 for the image forming device, a temperature detecting means 31 and a humidity detecting means 32 are installed, and ambient temperature and humidity detecting signals by the detecting means 31 and 32 are transferred to a control means, and the DC component VDC of a separation voltage by a separating means 19 is controlled by the control means in a range from a positive polarity to a negative polarity. And also, a detecting means 34 for detecting the electric resistance of a transfer material P is installed on a transfer material feeding path 17, the electric resistance value by the detecting means 34 is controlled by the control means 33, and the DC component VDC of the separation voltage by the separation means 19 is controlled by the control means in the range from the positive polarity to the negative polarity. |
