Abstract: A fusing device is provided for use in an image forming apparatus to fuse a toner image having a polarity on a printable medium. Such a fusing device comprises: a heating roller which comprises a heat source; a driving roller which is spaced apart from the heating roller; a fusing belt which travels on the heating roller and the driving roller and is heated by the heating roller; a pressing roller which forms a fusing nip against a surface of the fusing belt and presses the printable medium to the fusing belt; and a power supply which applies a voltage to the pressing roller to electrify the printable medium into a polarity opposite to the polarity of the toner image.

Abstract: A fusing device of an image forming apparatus which applies principles of leverage, and an image forming apparatus containing such a device. The fusing device includes a fusing unit having a heating roller and a pressure roller facing each other and which rotate together, a cover which opens and closes the fusing unit, and a pressure and release unit, one end of which is rotatably fixed to a rotating shaft, the pressure and release unit containing a member having a pressuring unit which pressures the pressure roller towards the heating roller when the cover opens and shuts, and a pressured part, which is farther from the rotating shaft than the pressuring part and which receives pressure from the cover.

Abstract: An image forming apparatus includes a scanning unit for reading images of a document, and a printing unit that includes an exposing unit to form an electrostatic latent image corresponding to the image read by the scanning unit. The exposing unit is mounted on the scanning unit to be moved with the scanning unit when the scanning unit rotates with respect to the printing unit.

Abstract: A combination machine having an image data conversion function. The combination machine has at least two modules among a scanner module to project light onto documents and produce images, a photocopier module to output the images onto paper, and a facsimile machine module to send images through a communication channel and to receive images through the communication channel, including a character recognition part to recognize characters on the images, a translation part to translate the recognized characters into a different language, and a controller to control the character recognition part and the translation part to translate the images into the different language and to convert the characters translated in the different language into images. Accordingly, the combination machine can translate images with respect to text on documents, convert the images into a voice, and convert into an image format processable by an external display device on a user's single command.
