Image forming apparatus
An image forming apparatus includes a recording head having a nozzle surface including plural nozzles configured to eject liquid droplets, a suction cap configured to seal the nozzle surface of the recording head, a cap holder configured to displaceably hold the suction cap via an elastic member and retractably disposed corresponding to the recording head, and a wiping member configured to wipe the nozzle surface of the recording head in a direction from an upper side to a lower side. The cap holder is provided with a guide part configured to come into contact with an upper end surface of the recording head to frictionally move on the upper end surface of the recording head, and the guide part is disposed on an upper side of the recording head.
1. An image forming apparatus comprising:
a recording head having a nozzle surface including a plurality of nozzles configured to eject liquid droplets;
a suction cap configured to seal the nozzle surface of the recording head;
a cap holder configured to displaceably hold the suction cap via an elastic member and retractably disposed corresponding to the recording head; and
a wiping member configured to wipe the nozzle surface of the recording head in a direction from an upper side to a lower side, wherein
the cap holder includes a guide part disposed on an upper end of the cap holder to come into contact with a side surface of an upper end of the recording head to frictionally move on the side surface of the upper end of the recording head together with the cap holder,
the guide part is a plate-like member that projects from the upper end of the cap holder in a direction parallel to a liquid ejecting direction of the nozzles, and
the guide part is disposed on an upper end side of the cap holder and not disposed on a lower end side of the cap holder.
2. The image forming apparatus as claimed in claim 1 , wherein
the recording head includes a nozzle cover configured to cover a peripheral part of the nozzle surface and an outer peripheral surface of the recording head, and
the nozzle cover covers an upper part of the outer peripheral surface and side surfaces of the outer peripheral surface, and does not cover a lower part of the outer peripheral surface of the recording head.
3. The image forming apparatus as claimed in claim 2 , wherein
the nozzle cover is downwardly projected from the lower end surface of the recording head.
4. The image forming apparatus as claimed in claim 1 , further comprising:
a liquid receiving member disposed below the recording head and configured to receive a liquid dripping from the suction cap side and the recording head side.
5. The image forming apparatus as claimed in claim 1 , further comprising:
a liquid receiving surface disposed below the recording head in parallel with the nozzle surface and configured to receive a liquid scattered by causing the wiping member to complete a wiping operation.
6. The image forming apparatus as claimed in claim 1 , further comprising:
an integral member formed of a liquid receiving member and a liquid receiving surface, the liquid receiving member being disposed below the recording head and configured to receive a liquid dripping from the suction cap side and the recording head side, the liquid receiving surface being disposed below the recording head in parallel with the nozzle surface and configured to receive a liquid scattered by causing the wiping member to complete a wiping operation.
