Problems solved by technology

[0014] However, when heating by a heating source embedded inside a dense medium, for example, a heating medium having its surface coated with a resin on its surface, since resin generally has low thermal conductivity compared with metal, it is easy to cause heat loss on the surface of the heating medium and temperature difference between internal
Such a tendency becomes more remarkable when the resin thickness becomes thicker and in this case, not only is it difficult to arrange energy saving requirements, but also the adhesiveness of the fluorine-containing resin to the heating medium tends to be easily reduced, and thus shortens the heating time. Media life
[0015] On the contrary, in the case of thinning the resin film on the surface of the heating medium, the above-mentioned fluorine-containing resin coating is easily worn out, making it difficult to stably maintain the low energy of the surface of the heating medium for a long time

Embodiment 1

[0514] A copier (trade name: Modified Vivace 555 model as an evaluation device, fusing temperature set to 180°C, manufactured by Fuji Xerox Co., Ltd.), a fusing roller (1) arranged as a fusing roller, and an electrostatic latent image developer (1) were used. ) as a developer for image evaluation.

[0515] The evaluation was performed as follows: image formation was performed while adjusting the image density to control the amount of toner transfer to the recording medium surface to be 4.5 g / m 2 , S paper and J paper manufactured by Fuji Xerox Co., Ltd. were used as paper (recording medium), and the summer environment (30°C / 85%RH) and winter environment (10°C / 15%RH) were repeated for every 2,000 sheets ), the contact angle of the fuser roll to water at 25°C was measured per 10,000 sheets and the fuser roll peel performance from paper, occurrence of offset, and other image defects were evaluated. Duplicate copies for 30,000 sheets.

[0516] Along with the respective data of t...

Embodiment 2

[0518] The copy test and the same evaluation were performed in the same manner as in Example 1, except that the electrostatic latent image developer (2) was used instead of the electrostatic latent image developer (1).

[0519] The results are shown in Tables 1 and 2.

Embodiment 3

[0521] The copy test and the same evaluation were conducted in the same manner as in Example 1, except that the electrostatic latent image developer (3) was used instead of the electrostatic latent image developer (1).

[0522] The results are shown in Tables 1 and 2.

Abstract

The present invention provides an image forming method comprising the steps of forming an electrostatic latent image on a surface of an electrostatic latent image bearing body, forming a toner image by developing the electrostatic latent image by using a toner, transferring the toner image to the surface of a recording medium, and fusing the transferred toner image on the surface of the recording medium by bringing the toner image into contact with a heating medium, which has a resin coating layer formed on the surface thereof, and thereby melting the toner image. The toner contains a binder resin containing monomers having vinyl double bonds. A storage elasticity of the toner at 180 DEG C. is in a range of 1x10<3>to 8x10<3> Pa and a contact angle of the surface of the heating medium to water at 25 DEG C. is in a range of 50 to 100 DEG .

Description

technical field [0001] The present invention relates to an image forming method for developing an electrostatic latent image formed by electrophotography, electrostatic recording, etc. and providing a high-quality image by subjecting the electrostatic latent image to the respective steps of development, transfer, and melting. Background technique [0002] Like electrophotographic methods, methods of displaying image information by electrostatic latent images are currently widely used in various fields. Regarding the electrophotographic method, the electrostatic latent image on the surface of the photoreceptor is subjected to a charging process and an exposure process to be developed with a toner for developing the electrostatic latent image (hereinafter, sometimes referred to as a toner), and then subjected to a transfer process. Printing process, melting process, etc. to develop electrostatic latent image. [0003] As developers to be used in such a method, two-component d...
