<P>PROBLEM TO BE SOLVED: To apply a shock absorbing function to a mover at a low cost without adding an additional braking device. <P>SOLUTION: In a cover 200 to which a write device 150 of an image forming apparatus 100, the rotary motion of a shaft body 202 is operatively connected with a heat roller 170 through a one-way clutch 310 only in the closing operation. A pressure roller 180 is brought into pressure contact with the heat roller 170 and driven to rotate, whereby braking force is applied to the heat roller 170. Thus, in the closing operation state, braking force is applied to a door member 201, so that in closing the cover 200, no shock is not applied to the write device 150. <P>COPYRIGHT: (C)2010,JPO&INPIT |
