To provide an image forming device capable of preventing excessively less loading or excessive loading for the storage capacity of a paper delivery tray even when paper sheets are conveyed in a curled state, and realizing the consistent paper delivery without the stacked paper sheets being caught in a paper delivery roller.
The image forming device 1 comprises an image forming unit 10, a fixing unit 30, a paper feed cassette 23, and a paper sheet conveying unit 59 for conveying paper sheets, and further comprises a paper delivery unit 22 having a paper delivery roller 19 for delivering the paper sheets with a developer image fixed thereto, and a paper delivery tray 22a for storing the paper sheets, and outputs image information by the electro-photographic system. The image forming device also has a curl detection sensor 222 for detecting the curled state of the paper sheets to be conveyed to the downstream side of the paper sheet conveying direction of the fixing unit 30 of a paper delivery conveying passage 17 through which the paper sheets are passed, and performs the paper delivery based on the output signal from the curl detection sensor 222.
