Abstract:
A direct image-recording device in which a predetermined gap set between an image carrier and a hole forming member can be maintained, and an image forming apparatus provided with the direct image-recording device. In the direct image-recording device including: housing that accommodates an agent; an agent carrier that is rotatably supported by the housing and faces outside from an opening formed in the housing; a sheet-like hole forming member having a plurality of holes formed therein and facing the agent carrier at a predetermined distance therefrom; and a plurality of electrodes, by which the agent flies, provided at the hole forming member correspondingly to each of the plurality of holes and form an electric field causing the agent to fly selectively from the agent carrier toward the hole, a positioning member is provided at the housing so as to cover the agent carrier, the positioning member being configured to hold the hole forming member along the axial direction of the agent carrier by a side wall of the positioning member that has open portions formed in locations at least opposing the plurality of holes formed in the hole forming member, and configured to position the holes relative to the agent carrier so that the relative positions of the agent carrier and the holes are in a predetermined positional relationship.
