Abstract: A four-color liquid crystal display device has pixels containing first to fourth subpixels (hereinafter abbreviated as “SPs” as needed) having four different colors, respectively, arranged in a two-by-two matrix, the first to fourth SPs being placed in the first row and the first column, in the first row and the second column, in the second row and the second column, and in the second row and the first column, respectively. In displaying a font (i) subjected to subpixel rendering premised on a pixel composed of three SPs having three different colors, respectively, arranged in three columns of stripe, and (ii) specified, regarding a predetermined pixel falling on part of a character edge, that the SP in the first column takes on a tone Tx, that the SP in the second column takes on a tone Ty, and that the SP in the third column takes on a tone Tz, the liquid crystal display device specifies, for the predetermined pixel, that each of the first and fourth SPs takes on a tone which is obtained by performing rounding on (Tx×⅔)+(Ty×⅓)=p and that each of the second and third SPs takes on a tone which is obtained by performing rounding on (Ty×⅓)+(Tz×⅔)=v. This allows the four-color liquid crystal display device to appropriately display a subpixel rendered font (e.g., Clear Type (registered trademark)).

Abstract: Pixel circuits 6 have a rectangular shape longer in an extending direction of scanning signal lines than in an extending direction of data signal lines. Three pixel circuits 6 arranged in the extending direction of data signal lines form one pixel. A pixel having three pixel circuits 6 arranged in the order red, green, and blue, a pixel having three pixel circuits 6 arranged in the order green, blue, and red, and a pixel having three pixel circuits 6 arranged in the order blue, red, and green are repeatedly arranged in the extending direction of scanning signal lines. By this, when line inversion drive is performed using a data signal line drive circuit 4, voltages of different polarities are applied to three types of pixel circuits 6 in each line in each frame to cancel out the influence of the polarities of the applied voltages, thereby suppressing a color shift.

Abstract: A fixing unit 8 is fitted with a rail 28 along which a rail guide provided inside an image forming apparatus can slide. This allows the fixing unit 8 to be extracted out of the image forming apparatus. When the fixing unit 8 is extracted out of the image forming apparatus, a transferring body separating member 26, which has thus far been prevented from rotating by the rail 28, is made to rotate by the force applied by a tension spring 27. An end portion of the transferring body separating member 26 presses a transfer roller bracket 24 and thereby moves a transfer roller 17. Thus, the transfer roller 17 is separated from a photoconductor drum 2.
