Visible image forming device and image forming apparatus
View Patent ↗An image forming apparatus includes an image carrier, a developing device, a developer container and a hole connection member. The developing device is provided so as to be movable in a direction in which it comes close to and goes away from the image carrier. And, the developing device develops a latent image formed on the surface of the image carrier into a visible image. The hole connection member is supported so as to be movable relative to an inlet of the developing device in the movable direction of the developing device and connects the inlet and an outlet of the developer container.
1. A visible image forming device comprising:
an image carrier;
a developing device that is provided to be movable in a direction in which the developing device comes close to and goes away from the image carrier, and that serves to develop a latent image formed on a surface of the image carrier into a visible image, wherein the developing device comprises:
a developing device container that transports developer inside the developing device container;
a developer carrier that is opposed to the image carrier, and holds developer supplied from the developing device container on a surface of the developer carrier; and
an inlet through which developer flows into the developing device container;
an urging member that urges the developing device in such a direction that the developing device comes closes to the image carrier;
a contact subject portion that is integral with the image carrier;
a contact portion that is provided in the developing device, and that contacts the contact subject portion, wherein an interval is kept between the image carrier and the developer carrier at a preset value; and
wherein the inlet is connected to an outlet through which developer flows out of a container main body so as to be movable relative to the outlet in the movable direction of the developing device.
2. An image forming apparatus comprising:
an image carrier;
a developing device that is provided to be movable in a direction in which the developing device comes close to and goes away from the image carrier, and that serves to develop a latent image formed on a surface of the image carrier into a visible image, wherein the developing device comprises:
a developing device container that transports developer inside the developing device container;
a developer carrier that is opposed to the image carrier, and holds developer supplied from the developing device container on a surface of the developer carrier; and
an inlet through which developer flows into the developing device container;
an urging member that urges the developing device in such a direction that the developing device comes closer to the image carrier;
a contact subject portion that is integral with the image carrier;
a contact portion that is provided in the developing device, and that contacts the contact subject portion, wherein an interval is kept between the image carrier and the developer carrier at a preset value; and
a developer container that is detachably mounted in a mounting unit which is integral with a support frame which supports the image carrier, wherein the developer container comprises:
a container main body that contains developer to be supplied to the developing device container; and
an outlet, opposed to the inlet, through which developer flows out from inside the container main body, wherein
the inlet is connected to the outlet so as to be movable relative to the outlet in the movable direction of the developing device.
3. The image forming apparatus according to claim 2 , further comprising:
a hole connection member that is supported so as to be movable relative to the inlet in the movable direction of the developing device and that connects the inlet and the outlet; and
an inlet opening/closing member that is supported by the hole connection member so as to be movable between an opening position where the inlet opening/closing member opens the inlet and a closing position where the inlet opening/closing member closes the inlet.
4. The image forming apparatus according to claim 2 , further comprising:
a first sealing member that is provided between a hole connection member and the inlet, and that seals a space between the hole connection member and the inlet; and
a second sealing member that is provided between the hole connection member and the outlet, and that seals a space between the hole connection member and the outlet.
