    摘要: An image forming apparatus has a plurality of print assemblies for forming a color image, a fixing unit, and a paper conveyor belt for conveying a paper sheet through the print assemblies and the fixing unit. The fixing unit includes a pair of fixing rollers, a nip control mechanism for moving the pair of the fixing rollers between a nip position and a non-nip position, and a fixing unit securing member movable with the nip control mechanism. Thus, the fixing unit can be easily mounted and demounted.

    摘要: An image forming apparatus which includes a frame, a top cover pivotally mounted to the frame, a lock member for locking the top cover onto the frame, a plurality of printing assemblies, a fixing device, and a paper conveyer belt. Each of the printing assemblies includes a photosensitive body, a charger, an optical head for forming an electrostatic latent image on the photosensitive body, a developing device, and a transfer element. The optical heads are mounted to the top cover. A cover lifting mechanism is provided for lifting the top cover by a predetermined amount relative to the frame when the lock member is released. The lifting mechanism includes a spring loaded rod which is linked to a cover releasing button.
