<p>The invention relates to an impact dot head and an image forming device. A structure of the impact dot head can be simplified and the impact dot head can be assembled easily. The impact dot head comprises an armature (25) which is configured in a freely swing manner, a print needle (26) which is mounted at the front end of the armature (25); an electromagnet which is arranged corresponding to the armature (25) and generates an electromagnetic force to attract the armature (25), first force-applying portions which are arranged corresponding to the armature (25) and apply forces to a direction enabling the armature (25) to return to an initial state by using first forces, with the rotation of the armature (25), and second force-applying portions which are arranged corresponding to the armature (25) and apply the forces to the direction enabling the armature (25) to return to an initial state after the armature (25) starts to rotate. Each second force-applying portion forms a force-applying component. Since each second force-applying portion forms a force-applying component, the impact dot head can be assembled easily.</p> |
