Abstract
An image forming device includes a photosensitive unit, a developing unit, and a positioning unit. The photosensitive unit is configured to support a photosensitive body. The developing unit includes a developer carrying body and a unit case. The positioning unit configured to adjust a positional relationship between the developer carrying body and the photosensitive body. The positioning unit includes a separating unit configured to separate the developer carrying body from the photosensitive body, and a high pressure unit configured to provide a high pressure contact between the developer carrying body and the photosensitive body. A pressure in the high pressure contact is higher than a pressure in a normal pressure contact. The normal pressure contact is such a pressure that the developer carrying body and the photosensitive body are held during a printing operation.
