Definitions
- the present invention relates to an electrostatic image developing toner used for electrophotography, electrostatic recording, and the like.
- an image forming apparatus such as an electrophotographic copying machine or a printer forms a latent image on a photoconductive photoreceptor and forms a carrier or a part of a developing device on the latent image.
- Insulating toner which has obtained triboelectric charge due to friction with the formed charging member, is electrostatically attached and developed, and then the formed toner image is transferred to a transfer medium such as plain paper or film, and then heated.
- the basic principle is to form a copy image or a print image by fixing the toner image with pressure, solvent vapor or the like.
- a heat roll fixing method is generally used because of its high thermal efficiency and high-speed fixing.
- a transfer paper is brought into contact with a heating roll in a fixing machine having a heating roller to fix the toner.
- a so-called offset phenomenon occurs in which a part of the toner adheres to the surface of the heating roll at the time of fixing, and the toner re-transfers onto the paper to stain a subsequent image.
- the transfer paper is wound on the surface of the heating roll to cause a paper jam, and a so-called winding phenomenon occurs.
- the viscoelastic properties of the toner are determined by the type of binder resin, which is the main component of the toner, and the type and content of other components.
- Styrene-acrylic resins and polyester resins are generally used as the binder resin, which is a main component of the toner.
- a cycloaliphatic resin (cycloolefin resin) has been studied.
- the alicyclic olefin resin is colorless and transparent, has low-temperature fixability and high-speed fixability provided by good thermal properties, sharp molecular weight distribution, It has various excellent properties such as good pulverizability (high productivity, sharp particle size distribution), low moisture absorption, and no pollution, so it is a binding alternative to styrene-acrylic resin and polyester resin. It is expected as a resin.
- the alicyclic olefin resin generally has a narrow molecular weight distribution, so that when fixing the toner, an offset phenomenon or a winding phenomenon occurs, and the fixing characteristics on the high temperature side are not sufficient immediately. There is.
- the moldability of the toner is not sufficient.
- the above problems are more likely to occur as the amount of the release agent introduced increases. Therefore, it is difficult to improve the fixing properties such as the offset phenomenon and the winding phenomenon without lowering the properties such as the anti-fusing property only by introducing the release agent.
- the term "formability" refers to the ease of producing toner particles in which the raw materials are well dispersed and which can be easily pulverized.
- Patent Document 1 JP 2003-114546 A
- Patent Document 2 JP 2001-272816 A
- Patent Document 3 JP-A-10-73959
- JP-A-2003-114546 discloses that a binder resin contains at least a cycloolefin copolymer resin, and a wax added as a release agent contains 7 to 20% by weight based on the total weight of toner particles. Further, there is disclosed a full-color toner for fixing without fixing, wherein the glossiness of a printed image surface is 15 or more.
- Cycloolefin copolymer resins include, for example, hyalephine (acyclic olefin in a broad sense) such as ethylene, propylene, and butylene and an alicyclic ring having a double bond such as cyclohexene, norbornene, and tetracyclododecene. This is a copolymer with a formula compound (cycloolefin).
- the cycloolefin copolymer resin is, for example, a polymer obtained by a polymerization method using a meta-mouth catalyst or a Ziegler catalyst. It is.
- the toner particles may fuse with each other, or the charging of the developing device may be performed. Because the toner is fused to the member, the fusion resistance of the toner is likely to deteriorate. Further, according to this method, it is not easy to uniformly disperse and finely disperse a large amount of low molecular weight components in the binder resin during the production of the toner, so that the moldability of the toner is not sufficient. When the dispersibility is low as described above, the fusion resistance tends to deteriorate. Disclosure of the invention
