Title: Picture image forming device
Inventor: KAI SO
IPC: G03G21/18
Filed: 1990-11-30
Abstract: PURPOSE:To prevent staining a perimeter without dispersing toner due to minimum separation of a gap from a photosensitive body by separating a casing from an image carrier at only an attaching and detaching position of the carrier in a transfer supporting means. CONSTITUTION:The integrated rotation in a counterclockwise direction of first and second casings 102 and 103 and a photosensitive body belt 1 of a device causes a free moving end part of the second casing 103 to come to stay roller 302 and to begin opening with the second casing 103 pressedly contacted with a stay roller 302. On the other hand, the first casing 102 facedly contacts a checking roller 304 following a checking roller 303 to retain a closed condition. A shutter 240 is moved so as to close an opening 236a as the second casing 103 parts from a horizontal part 1b of the photosensitive body belt 1, and the opening 236a is completely closed. The casing 102 is completely closed. The casing 102 is never parted from the photosensitive body belt 1, causing a shutter 168 to be left opened. This eliminates staining an operator body or a room due to toner leakage because the opening 236a is closed with the shutter and is located on the upper surface side.
