Image formation apparatus |
摘要 |
An image formation apparatus includes: an image carrier; an exposure unit; a developer container part; a developer supply unit; a development unit; a remaining amount detector which detects a remaining amount of the developer in the container part; a development voltage application unit which applies a development voltage to the development unit; a supply voltage application unit which applies a supply voltage to the supply unit; and a voltage controller which controls the development voltage and the supply voltage. When the remaining amount of the developer detected by the remaining amount detector is reduced to a predetermined first threshold or less, the voltage controller makes an absolute value of a difference between the development voltage and the supply voltage smaller than that used when the remaining amount of the developer is larger than the first threshold. |

1. An image formation apparatus, comprising:
an image carrier; an exposure unit which exposes the image carrier to form a latent image; a container part which stores a developer; a supply unit which supplies the developer within the container part; a development unit which supplies the developer supplied from the supply unit to the latent image on the image carrier for development; a remaining amount detector which detects a remaining amount of the developer in the container part; a development voltage application unit which applies a development voltage to the development unit; a supply voltage application unit which applies a supply voltage to the supply unit; and a voltage controller which controls the development voltage and the supply voltage, wherein when the remaining amount of the developer detected by the remaining amount detector is reduced to a predetermined first threshold or less, the voltage controller makes an absolute value of a difference between the development voltage and the supply voltage smaller than that used when the remaining amount of the developer is larger than the first threshold. |
