Image forming apparatus having a fixing device attachable and detachable from a housing and a shutter movable between an open and close position

Abstract

An image forming apparatus includes a fixing device and a main housing. The main housing includes a contact portion that contacts the fixing device. The fixing device includes a fixing device housing having an opening, a shutter configured to move between an open position in which the shutter opens the opening and a close position in which the shutter closes the opening, a spring, and a moving member interlocking with the shutter that moves between a first position and a second positon. In a process of attaching the fixing device to the main housing, the moving member moves from the first positon to the second positon, thereby causing the shutter to move to the open position against the biasing force of the spring. In a process of detaching the fixing device from the main housing, the biasing force of the spring causes the shutter to move to the close position.
