A fixing apparatus includes a heating section including a belt having a layered structure in which a metal layer is held between nonmetal layers. The belt has a front surface that comes into contact with a toner image and a back surface that does not come into contact with the toner image. The belt has a first thickness from the front surface to the metal layer inside the belt and a second thickness from the back surface to the metal layer inside the belt. The fixing apparatus also includes a pressure section that holds, between the pressure section and the belt, a transported sheet of paper holding the toner image and that applies pressure to the sheet of paper. The fixing apparatus further includes a first static eliminating section that eliminates static from the belt while being in contact with a surface of the belt. The surface is the front surface or the back surface that is on a side of the first thickness or the second thickness having a smaller thickness when the first thickness and the second thickness are compared.

Fixing apparatus and image forming apparatus

When ink is discharged more than once to one pixel area, the ink is discharged without focusing on specific scans among a plurality of scans if the attribute in an image is a first attribute, and the ink is discharged intensively in specific scans among the plurality of scans if the attribute in the image is a second attribute.

Provided is a printing method for multi-pass printing with column thinning in which the multi-pass number is not restricted to being a multiple of the column thinning number. A mask pattern of a size corresponding to the number of printing elements in use is prepared, and divided into blocks 1 to P. Taking R(x) to be the mask pattern for the region corresponding to block x (where x=1 to P), these P block mask patterns satisfy the following condition. Namely, for all integers s obtainable between the values from 1 to M, the arrangements of printing pixels exist in a complementary relationship with each other in the combination of mask patterns R(s), R(s+M), R(s+2M), and so on to R(s+N&#xd7;M). However, for all s, N is taken to be the largest integer satisfying s+N&#xd7;M&#x2266;P.

In a high print resolution, high image quality mode and a low print resolution, high speed mode, image processes are made in common between them to the extent possible, and the same gradation characteristics and image densities can be obtained between them. For this purpose, for the high image quality mode, a dot arrangement pattern is prepared for a pixel region having gradation data of K levels, which determines the presence or absence of print dots at K-1 areas, and in which the printing of 1 dot is permitted at all of the K-l areas. On the other hand, for the high speed mode, a dot arrangement pattern which determines the presence or absence of print dots at a number of areas less than K-1 is prepared, and in which the sum of the number of dots permitted to be printed at the pixel region is K-1.
