Problems solved by technology

However, the manual lever is inconvenient when the user removes the jammed printable media because the user must directly operate the manual lever with the hand
The motor-drive mechanism also increases manufacturing costs due to the installation of an additional drive source

Abstract

An image forming apparatus and a fixing unit thereof are disclosed. The fixing unit includes a heating roller, a press roller mounted in close contact with the heating roller to apply heat and pressure to the printable medium with the heating roller, a press lever to press the press roller toward the heating roller, a press spring connected to the press lever, a release device to operate the press lever to release pressing force exerted on the press roller, and a power conversion device to transmit driving power generated from a main driving source to drive the heating roller to the release device. Accordingly, since the press lever pressing the press roller to closely contact the heating roller can be operated by the driving power of the main driving source, the jammed printable medium can be easily removed.

Description

technical field [0001] The invention relates to an imaging device, in particular to an electrophotographic imaging device and a fixing unit thereof. Background technique [0002] An image forming device is a device that prints a black-and-white image or a color image on a printable medium, such as paper, according to an image signal. Examples of image forming devices include laser printers, inkjet printers, copiers, multifunction printers, and facsimile machines. Imaging devices can be divided into electrophotography and inkjet: the former scans the light beam onto the photoreceptor to form an electrostatic latent image, and the developer is attached to the electrostatic latent image, and the developer is transferred to the printable medium; the latter is based on The image signal jets liquid ink onto the surface of the printable media. [0003] An electrophotographic image forming device is configured such that a surface of a photoreceptor is charged with a predetermined ...
