PROBLEM TO BE SOLVED: To provide an image forming device capable of adjusting the pitch of pressure developing balls without depending on the high accuracy of parts. SOLUTION: A carriage 48 is provided with a fixed pressure developing member 112 provided with pressure developing balls 111 and a movable pressure developing member 113 which is provided with the ball 111 and can be adjusted and moved. Then, the movable pressure developing member 113 is pressed in the direction where it approaches the reference surface 48a of the carriage 48 by a spring member 116 and moved by resisting the pressing force of the spring member 116 and with the rotation of an eccentric cam member 117 to adjust the pitch of the pressure developing balls 11 of each of the pressure developing members 112 and 113 in the feeding direction of a microcapsule paper. |
