To make it possible to remove an oil application device to a fixing roll in a hot roll fixing device using a liquid developer, and to save the trouble of oil supply. By mixing in a certain proportion of nonflammable liquid, the risk of ignition is reduced. [Structure of the Invention] In recent years, hot roll fixing has been proposed as a method of fixing a liquid developer that has high thermal efficiency and is capable of high-speed fixing. By using a hydrocarbon-based solvent as the carrier liquid and adopting this fixing method, the amount of solvent gas emitted per unit number of sheets is slightly reduced compared to the conventionally used atmospheric fixing, but it is possible to copy a large number of sheets at high speed. When this happens, a large amount of solvent gas is generated. Furthermore, it was necessary to apply silicone oil to improve the releasability between the toner layer and the fixing roll. The present invention aims to improve the above-mentioned drawbacks, increase the cohesive force of the toner, and prevent so-called "hot offset" by containing a fluorine-based solvent as a carrier liquid. Fluorinated solvents used in the present invention include Fluorinert FC-77, FC-40, FC-43, FC-70
(Manufactured by 3M Company), Afroud, E-10, E-1
6, E-18 (manufactured by Asahi Glass Co., Ltd.), and the like. Further, as silicone-based solvents that may be used at the same time, KF96 (Shin-Etsu Silicon J-Con), 5H200, 5H3
44 (Toshiba Silicon), TSF451 (Toshiba Silicon), etc. In addition, decamethyltetrasiloxane, octamethyltrisiloxane, etc. may be used. In addition, cyclohexane, n-

Petroleum hydrocarbons such as isooctane, isododecane, ligroin, and mixtures thereof (commercially available products include Isopar E, G, H, L, and V manufactured by Exxon Chemical Co., Ltd., and Shellsol 71 and Solupesso 150 manufactured by Shell Oil Co., Ltd.) ), and these may be mixed and used as appropriate. In order to reduce the amount of transfer agent, the carrier liquid should be 10 cst or less, preferably 3 cst or less. In the present invention, one way to increase the cohesive force of the toner is to provide the toner resin component with an acid-base interaction. In the present invention, acid-base interactions are formed within a single polymer or between two or more polymers. Although the details of how acid-base interactions are formed between polymers are unknown, it is likely that acidic and basic functional groups in the polymer are attracted to each other, resulting in a type of interaction. It is thought that by creating an association state, it apparently behaves like a resin molecule. It is believed that the acid-salt reaction between the functional groups forms a weak crosslinking state, which improves offset resistance while keeping the fixing temperature low. Acidic groups that cause such association include carboxylic acids,
There are groups such as sulfonic acid, phosphonic acid, and sulfinic acid, and basic groups include hydroxyl group, pyridyl group, and amino group. A polymer having one type or two or more of these acidic groups and basic groups can be used in the present invention, and the polymer can be prepared by polymerization or copolymerization from monomers having the above-mentioned functional groups. It is created by synthesis or by introducing the above-mentioned functional group into a polymer through reaction. Examples of monomers having the above-mentioned functional groups include acrylic acid and its derivatives such as acrylic acid, methacrylic acid, α-ethyl acrylic acid, crotonic acid, and isocrotonic acid; maleic acid, fumaric acid, itaconic acid, citraconic acid, etc. Unsaturated dicarboxylic acids and derivatives thereof; For example, aminoalkyl acrylates and aminoalkyl methacrylates such as diethylaminoethyl methacrylate; For example, vinylpiperidine, vinylpyrazine, vinylpyridine, etc.; For example, aminostyrene, dimethylaminostyrene,

Production Example 3 Synthesis was carried out in the same manner as Production Example 1, except that 60 parts of styrene, 10 parts of methyl methacrylate, 20 parts of butyl acrylate, 10 parts of methacrylic acid, and 0.7 parts of divinylbenzene were used as monomers. Mw/Mn was 40 and Mw was 324,000. Example 1 70 parts of the resin of Production Example 1 50 parts of the pulverized product 200 parts of Isopar H (trade name of EXXSON) were placed in a ball mill and dispersed for 24 hours, and then 300 parts of Isopar H was added and dispersed for 1 hour. It was made into a concentrated toner. 200 g of this was taken and diluted in a mixed solvent 1a of 50% Fluorinert FC-72 (manufactured by 3M Co., Ltd.) and 50% KF96 (manufactured by Shin-Etsu Silicone Co., Ltd., viscosity 3cst) to prepare a developer.

10 parts of 00A (manufactured by Allied Chemical Co., Ltd.) and 30 parts of Sorel 40o (manufactured by Cabot Company) were subjected to cross-wire pulverization at 140° C. for 60 minutes in a flasher. A developer was prepared in the same manner as in Example 1. An oil-less fixing test was carried out using a test machine, CT5085 manufactured by Ricoh, whose fixing unit was improved to a hot roll fixer. The results were as shown in the numerical table. As is clear from the above results, it can be seen that the developer of the present invention provides a temperature within the range in which heat roller fixation is possible without an offset phenomenon, and that heat roller fixation is possible. Continuous copying was performed using a test copying machine in a sealed room, and the solvent gas concentration was measured.
While it was 0 ppm, the developer of the present invention was halved to 80 to 150 ppm. [Effect 1] By using the developer of the present invention, it is possible to perform hot roll fixing without applying oil to the fixing roll and without causing an offset phenomenon, enabling high-speed, low-energy, constant fixing in a compact copying machine. It has become possible. Additionally, the amount of hydrocarbon gases generated by copying machines has also been reduced.
