Abstract
An image forming apparatus has a latent image forming unit for forming a latent image on an image carrying body and a developing unit for visualizing the latent image formed on the image carrying body by using a developer. In the image forming apparatus, for the developing unit, a developer replenishment box is communicatively connected to a developing housing in which a developer is contained, and the developer replenishment box is disposed in an upstream of a latent image writing position P on the image carrying body. The developer replenishment box is contained in a process cartridge.
Claims15
An image forming apparatus comprising:
- a latent image forming unit for forming a latent image on an image carrying body;
- and
- a developing unit for visualizing the latent image formed on the image carrying body by using a developer,
- wherein a developing housing containing the developer is communicatively connected to a developer replenishment box;
- and
- wherein the developer replenishment box is disposed in an upstream of a latent image writing position on the image carrying body.
An image forming apparatus comprising:
- a latent image forming unit for forming a latent image on an image carrying body;
- a developing unit for visualizing the latent image formed on the image carrying body by using a developer;
- and
- an intermediate transfer member for temporarily holding the visual image formed on the image carrying body and transferring the visual image onto a recording sheet,
- wherein the recording sheet is transported from a lower part to an upper part;
- wherein a developing housing containing the developer is communicatively connected to a developer replenishment box;
- and
- wherein the developing housing and the developer replenishment box are disposed in an upper part of a latent image writing position on the image carrying body.
A process cartridge comprising:
- an image carrying body;
- at least one process unit;
- and
- a developer replenishment box,
- wherein the developer replenishment box is communicatively connected to a developing housing;
- and
- wherein the developer replenishment box is disposed in an upstream of a latent image writing position on the image carrying body.
A developing unit comprising a housing for containing developer, wherein the housing is communicatively connected to a developer replenishment box.
