Description
Technical field
The present invention relates to a kind of imaging device and printing transferring method thereof, particularly relate to a kind of imaging device and printing transferring method thereof that utilizes magnetic printing transferring method to carry out transfer printing.
Background technology
Imaging device is a kind of the most frequently used computer peripheral equipment, mainly comprises laser printer, duplicating machine and Multi Role Aircraft etc.; They all need to carry out transfer printing in the course of the work, the developer imaging in photosensitive drums are transferred on print media; It is the characteristic of utilizing positive negative electricity to inhale mutually, by transfer roll, the conventional print media such as paper is applied to positive electricity, and electronegative developer in photosensitive drums is attracted and completes transfer process; Because existing imaging device is difficult to, to applying electric charge as thicker dull and stereotyped print media such as plastics, potteries, cannot complete the transfer printing to above-mentioned dull and stereotyped print media.
For the problems referred to above, prior art is to utilize improved ink-jet printer, and flat-panel printer, prints above-mentioned dull and stereotyped print media, and cannot utilize existing print speed and the better imaging device of print quality to print, limited the range of application of dull and stereotyped printing; The laser printer of below take describes the existing imaging device course of work as example, and Fig. 1 is the structural representation of transfer printing and photographic fixing part in existing laser printer, and this laser printer comprises handle box, transfer printing part and photographic fixing part; Handle box comprises powder storehouse 1, powder outlet cutter 2, developer roll 3, photosensitive drums 4, cleaning doctor 5, waste powder hopper 6 and charging roller 7; Transfer printing part comprises transfer roll 10, and photographic fixing part comprises fixing roller 8 and downforce roller 9; Groundwork process can be divided into charging, exposure, development, transfer printing, photographic fixing, seven steps such as electricity clean, disappear.(1) charging: 7 pairs of photosensitive drums of charging roller, 4 surface uniform ground chargings; (2) exposure: the laser through ovennodulation that laser scanner contains image information to photosensitive drums 4 transmittings, forms and the electrostatic latent image for the treatment of that duplicating image is corresponding on photosensitive drums 4 surfaces; (3) develop: due to the rotation of developer roll 3, the developer that developer roll 3 and powder outlet cutter are 2 because of spin friction charged, charged developer is again because the pressure extrusion thickness of powder outlet cutter 2 is evenly distributed on developer roll 3, when developer roll 3 rotates to the position corresponding with photosensitive drums 4, charged developer makes electrostatic latent image convert visual image to because the effect of electric field force is transferred on the surface of photosensitive drums 4; (4) transfer printing: along with the rotation of photosensitive drums 4, the positive voltage effect that the print media back sides such as 10 pairs of paper of transfer roll apply, to formed the electronegative developer of visual image at photosensitive drum surface, produce attractive force, the visual image being formed by developer is transferred on the print media such as paper; (5) photographic fixing: paper enters between the photographic fixing part being comprised of upper warm-up mill 8 and lower backer roll 9 subsequently, under the effect of heat and pressure, developer fuses into print media, so the visual image that developer forms solidifies completely and is recorded on print media; (6) clean: in 5 pairs of photosensitive drums 4 of cleaning doctor, residual developer cleans; (7) electricity that disappears: the residual charge that utilizes charging roller 7 to eliminate in photosensitive drums 4; Laser printer completes once and prints through these seven basic steps, repeats above-mentioned 7 steps and completes rapidly high-quality print job.
The imaging devices such as duplicating machine, facsimile recorder and Multi Role Aircraft, all comprise above-mentioned laser printer transfer printed document and photographic fixing part two parts, although not being the form with handle box, other parts do not exist, but all comprise the parts such as photosensitive drums, developer roll and charging roller, its transfer printing principle and process are identical with laser printer.If can be by changing the printing transferring method of these imaging devices, can carry out transfer printing to dull and stereotyped print media such as thicker pottery, plastics, can on these dull and stereotyped print media, print rapidly high-quality color character and image, and can simplify the printing technique to dull and stereotyped print media in prior art.
In addition, use existing laser printer to carry out in the technology of hot transfer printing, the paper that need to use hot transfer printing carries out coating processing, with after realizing developer and being transferred on paper, allows developer easily and paper is peeled off in being transferred to the process of object; If when using laser printer to carry out hot transfer printing, do not need the print media such as paper to carry out coating processing, even do not need the print media such as corresponding paper, can reduce the expense of this hot transfer printing and simplify corresponding technique.
