Example Embodiment

[0025] Now, an image forming method and an image forming apparatus according to an embodiment of the present invention will be described in detail here with reference to the accompanying drawings.

[0026] figure 1 The main part of the thermal printer 1 as an example of the image forming apparatus is illustrated. The image information is transmitted from an upper system including a digital device (for example, a personal computer or a digital camera) or a host computer to a control section (not shown) of the thermal printer 1 through, for example, a connection cable. Upon receiving the image information, the control section starts a recording operation to form an image on the sheet 3 as recording paper.

[0027] The sheet 3 accommodated in the paper feeding tray (feeding portion) 2 is pressed against the feeding roller 6 by the upper / lower plate 5 which swings up and down around the upper / lower plate shaft 4. The rotation of the feed roller 6 picks up the sheet 3. Then the sheet...

Abstract

An image forming apparatus includes upstream and downstream transport rollers for transporting a recording paper sheet. The upstream transport roller is disposed on the upstream side of a recording head while the downstream transport roller is disposed on the downstream side of the recording head. When forming an image on the first half area of the recording sheet, the upstream transport roller rotates and is responsible for transporting the recording sheet. When forming an image on the second half area of the recording sheet, the downstream transport roller rotates and is responsible for transporting the sheet. This structure provides printing without margins at the leading and trailing edges of the sheet. By adjusting the gap sizes between rollers in each of the upstream and the downstream rollers, the transport speed of the sheet is maintained constant so that high-quality print image can be obtained without uneven density in an image.

Description

technical field [0001] The present invention relates to an image forming method and an image forming apparatus for a printer apparatus and a facsimile apparatus including a recording head as a recording member. Background technique [0002] In general, an ink sublimation type printer that prints image information on a sheet of chemically-treated recording paper using a thermal transfer belt has a recording head and a platen roller. The platen roller presses the sheet against the recording head when an image is formed. Inside the recording head, a plurality of heating elements are arranged in rows, and rows are arranged in parallel. The heating element is selectively heated according to the image information, so that the ink on the ink ribbon is sublimated and the image information is transferred to the recording surface of the sheet. Thus, a printing operation is performed. [0003] In this configuration, the sheet conveyance mechanism includes a power feed roller and a c...
