Abstract
An image formation apparatus including: a two-component developer that contains toner and carrier; a photoconductor that forms a toner image by the two-component developer; and an intermediate transfer body to which the toner image on the photoconductor is transferred. The intermediate transfer body has a surface layer that is provided on a transfer surface of the intermediate transfer body onto which the toner image is transferred and that contains a first fluoropolymer. The carrier has a carrier core particle and a coat layer that is provided on a surface of the carrier core particle and that contains a second fluoropolymer. The toner is positively charged.
Claims15
An image formation apparatus, comprising:
- a two-component developer comprising a toner and a carrier;
- a photoconductor that forms a toner image using the two-component developer;
- and
- an intermediate transfer body to which the toner image on the photoconductor is transferred, the intermediate transfer body has a surface layer that is provided on a transfer surface of the intermediate transfer body onto which the toner image is transferred and that comprises a first fluoropolymer;
- the carrier has a carrier core particle and a coat layer on a surface of the carrier core particle and that comprises a second fluoropolymer;
- and the toner is positively charged.
An image formation apparatus, comprising:
- a two-component developer comprising a toner and a carrier;
- a photoconductor that forms a toner image using the two-component developer;
- and
- a fixing device which fixes the toner image that has been transferred from the photoconductor to a recording medium;
- a fixing member of the fixing device comprising a surface layer comprising a first fluoropolymer;
- the carrier comprises a carrier core particle and a coat layer on the surface of the carrier core particle that comprises a second fluoropolymer;
- and
- the toner is positively charged.
A method of forming an image comprising the steps of:
- providing a two-component developer comprising a toner and a carrier;
- using the two-component developer to form a toner image;
- transferring the toner image on the photoconductor to a member selected from the group consisting of an intermediate transfer body and a fixing device, the member having a surface layer that comprises a first fluoropolymer;
- using as the carrier a carrier having core particles and a coat layer on a surface of the carrier core particles and comprises a second fluoropolymer;
- and
- using positively charged toner.
An image forming device comprising:
- a photoconductor that forms a toner image using a two-component developer comprising a toner and a carrier;
- a surface layer that is part of means for transferring the toner image comprising a first fluoropolymer;
- the carrier comprises a carrier core particle and a coat layer on the surface of the carrier core particle that comprises a second fluoropolymer;
- and
- the toner is positively charged.
