Description

The image that is used for fixing banding pattern electrophotography receives the image formation method of thin slice and this thin slice of use

Technical field

The present invention relates to a kind of fixedly image reception thin slice and a kind of image formation method that uses this image to receive thin slice of banding pattern electrophotography of being applicable to.

Background technology

Xerography is a kind ofly to be used for duplicating machine and to have the Method of printing of the printer of higher print speed as the dry method output device.This xerography has a step: toner image is transferred to image receive material, and should by stationary installation (, comprising stationary roll or fixed band) this toner image be fixed on the image reception thin slice by image reception thin slice as heating and/or polishing head.There is multiple printer paper to can be used as electrophotographic printer paper such as general paper, comprises conventional paper and high-grade paper, and be intended for use to provide the electrophotographic image of the gloss image and the sense of taking a picture to receive thin slice.For example described in Japanese unexamined patent publication No. publication number 4-212168 and the 8-211645, this electrophotographic image receives thin slice and comprises that one has the thin slice of toner image receiving layer, is coated with thermoplastic resin on this layer.Yet, be easy to cause skew when this image receives when thin slice separates with fixed head, thereby often cause convey error.Therefore, described in Japanese unexamined patent publication No. publication number 11-52604,11-52605,11-52606 and 11-212292, release agent such as polysiloxane compound, fluoride or wax that suggestion will have certain stripping result join in this toner image receiving layer or the skin.

The amount of desirable release agent should be as far as possible little.This is because the amount of release agent in the toner image receiving layer is more little, and the photograph that the image that is coated with the toner image receiving layer receives thin slice is sympathetic good more.Yet the amount of release agent is optimized according to the electrophotographic method of stationary roll type, and such optimization always is not applicable to the electrophotographic method of fixed band type.That is, in the electrophotographic method of the stationary roll type of routine, image receives thin slice by stationary roll being heated and separating with stationary roll immediately through the short period.Therefore, the release agent that exists on the surface of toner image receiving layer only part helps image to receive separating of thin slice and stationary roll, and the discrete release agent that is present in the remainder of toner image receiving layer does not then participate in detachment process.Therefore receive thin slice at the image of the conventional electrical photographic means that is used for using the stationary roll type and need a large amount of relatively release agents, the result, image with toner accepting layer receives thin slice and loses its notable feature, i.e. glossiness, and the image that is provided has obviously different with photographic image.

On the other hand, the electrophotography image reception thin slice for the fixed band type is heated it when image receives when thin slice contacts with fixed band, and separates with fixed band after cooling.Therefore, before image received the thin slice cooling and separates, toner image receiving layer heated time was longer than the heated time of fixed band.In this processing procedure, be present in the release agent melted by heating in the toner image receiving layer discretely, separate with the toner image receiving layer under a stable condition according to type then.This release agent separates with the toner image receiving layer, be to be distributed on the surface of toner image receiving layer irregularly, through cooling be solidificated on the toner image receiving layer and form solid layer, nearly all like this release agent all helps image to receive separating of thin slice and fixed band.Therefore, if use the electrophotographic method of fixed band type, when selecting suitable release agent, wishing provides the image with enough separating effects to receive thin slice with more a spot of release agent.In other words, image receives thin slice and keeps its skew patience (this be interpreted as being meant stop toner image or the toner layer part reverse transition opposing degree to fixed band) and glossiness, and because the release agent of suitable selection type and optimised quantity provides the rich image of taking a picture and feeling.
