摘要:
It is an object of the present invention to provide a toner containing an ethyl acetate-soluble polyester component and an ethyl acetate-insoluble polyester component, wherein the toner is granulated in an aqueous medium, the ethyl acetate-insoluble polyester component is obtained by elongating and/or cross-linking a modified polyester resin during granulating and/or after granulating, the modified polyester resin is produced by condensation polymerization of an acid component and at least one type of diol compound selected from aliphatic diol and alicyclic diol in the presence of a catalyst, and the mass average molecular weight of the modified polyester resin is 10,000 to 100,000.

A color electrostatographic printer apparatus applies respective color separation toner images to a receiver member to form a color image. A fuser station fuses, or at least tacks, the color image to the receiver. A clear toner overcoat is then applied to the fused color toner image using an inverse mask, and enhanced glossing of the image is provided by a belt glosser to improve color gamut.

A fixing device includes i) two surface moving bodies, at least one of which is driven so that the surface moving bodies come in contact with each other, a nip is formed, and surfaces of the surface moving bodies in contact move in the same direction, and ii) a heat source configured to heat at least one of the surface moving bodies. A transfer medium having a surface where a non-fixed toner image is formed is put in the nip so that the toner image is heat-fixed on the transfer medium. The fixing device further comprises a separation plate configured to remove the transfer medium, the transfer medium not being separated from the surface moving body after the transfer medium passes through the nip, from the surface moving body. Rise of temperature of a head end part, at a side of the surface moving body, of the separation plate is given priority over rise of temperature of other parts of the separation plate.

Disclosed is a multilayer transfer belt for image-forming devices comprising a base layer (11), an elastic layer (intermediate layer) (12) and a surface layer (9) which has high surface resistivity, excellent toner releasability and excellent antifouling properties. The transfer belt for image-forming devices is characterized in that an elastic layer (12) containing an elastomer and a surface layer (9) composed of a fluorine-containing polymer are arranged on a base layer (11). The elastic layer (12) is preferably made of an ion conductive elastomer. Also disclosed is a transfer belt for image-forming devices further comprising a binder layer (14) between the elastic layer (12) and the surface layer (9) which is characterized in that the melting point of the material constituting the binder layer (14) is not more than the thermal decomposition point of the material constituting the elastic layer (12) and the thermal decomposition point of the material constituting the binder layer (14) is not less than the melting point of the material constituting the surface layer (9).
摘要:
The invention relates to a method and a heating device for heating at least one printing agent on a printing material (4), which is passed along a transport path through said heating device, comprising at least one microwave applicator (2) and at least one microwave absorber element in the outer perimeter of said microwave applicator. The object of the present invention is to reduce the loss of energy due to microwave radiation exiting from the microwave applicator (2). The object of the invention is achieved in that the minimum of one microwave absorber element is an irradiation device that absorbs microwave radiation and emits electromagnetic radiation, in which case said irradiation device, in accordance with the method herein, is energized by microwave radiation, applies radiation to the printing agent and/or the printing material (4), and thus at least aids the heating process.

An electrophotographic machine (10) includes a fusing station (60) configured for fusing an image to an image substrate (P) by applying fusing process parameters to the image substrate (P). A controller adjusts the fusing process parameters applied to the image substrate (P) dependent at least in part upon whether the image substrate (P) is to be processed by a glossing station (70) to thereby reduce undesirable image artifacts that result when an image contaminated with release fluid is fused and then glossed.
