IMAGE FORMING DEVICE

PURPOSE:To prevent a wrinkle from occurring on a paper in the case of pressure development by guiding hot blast generated by a hot blast generator to the inside of a paper feeding cassette set in a device main body from a passing hole. CONSTITUTION:The hot blast generator 11 is provided inside the device main body. One end of a duct 12 which is branched into two halfways is connected to the generator 11 and the other end of the duct 12 is linked with the cassette guiding member 13 of the device main body. After setting the paper feeding cassette C, a power source is turned on so that the hot blast generator 11 is actuated and the hot blast generated by the generator 11 is made to pass through the duct 12 and guided to the inside of the guiding member 13. Furthermore, the hot blast is guided to the inside of a cassette main body 1 from the passing hole 5a provided in the main body 1 so that the peripheral part of paper S accumulated in the paper feeding cassette C is forcibly dried with the hot blast. Thus, the wrinkle is prevented from occurring on the paper in the case of pressure development.
