PROBLEM TO BE SOLVED: To execute the whole operation of supply even when the opening/ closing angle of the front cover of an image forming device, which is opened/ closed at the time of exchanging the supply and at the time of performing jamming processing, can not be made large. SOLUTION: At the time of exchanging the supply and at the time of performing the jamming processing in a developing device 4, an arm 21a pulls a projection 25c interlocked with opening the front cover 21 in a direction shown by an arrow, and a transfer unit supporting member 25 starts to rotate. As the front cover 21 is opened further, the member 25 is pressed on the front cover 21 and widely opened when a spring 26 exceeds a dead point, and space in which the supply can be exchanged is formed. |
