本発明は、湿式電子写真複写機に用いられる液体現像剤
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a liquid developer used in a wet-type electrophotographic copying machine.
［従来の技術］

。これらは脂肪族炭化水素が主成分の担体液のため、そ
の脂肪族炭化水素のガスが複写機外へ排出される結果、
狭い室内での作業時あるいは連続複写時に不快臭を発生
する等環境への悪影響があった。[Prior Art] Conventionally, as a liquid developer for a heat roll fixing roll, JP-A-Sho Ei3-301968.301967.30197g

．． 50064.50065.5006B, 50087
．． 52167.142560.142581, etc. These are carrier liquids mainly composed of aliphatic hydrocarbons, and as a result of the aliphatic hydrocarbon gas being discharged outside the copying machine,
This had negative effects on the environment, such as producing an unpleasant odor when working in a small room or when making continuous copies.
他方、画像品質、省エネルギーの面から湿式トナーの定
着には熱圧ロールの使用か有効であるが、従来の湿式ト
ナーは、低粘度、低 率の材料を使用してきたため、
凝集力が弱く、熱ロール上にいわゆるオフセット現象を
生じやすく、実際の複写機のロール温度が不安定である
ため、画像品質も不安定なものであった。On the other hand, from the viewpoint of image quality and energy saving, it is effective to use a hot pressure roll for fixing wet toner, but conventional wet toner has used materials with low viscosity and low ratio.
The cohesive force is weak, so-called offset phenomenon tends to occur on the heated roll, and since the roll temperature of an actual copying machine is unstable, the image quality is also unstable.
また、トナー層と定着ロールとの離型性を上げるためシ
リコンオイルの塗布が必要であったが、そのために複写
機複雑になったり、消耗品点数が増すなどといった問題
があった。Furthermore, in order to improve the releasability between the toner layer and the fixing roll, it was necessary to apply silicone oil, but this caused problems such as making the copying machine more complicated and increasing the number of consumables.
［発明が解決しようとする課題］
本発明は、こうした実情に鑑み、連続複写を行っても不
快臭あるいはオフセット現象の発生がなく、また定着ロ

を提供することを目的とするものである。[Problems to be Solved by the Invention] In view of these circumstances, the present invention provides a liquid developer that does not cause unpleasant odor or offset phenomenon even when continuous copying is performed, and that can omit oil application to the fixing roll. The purpose is to provide the following.
［課題を解決するための手段］
本発明者らは前記した課題を解決すべく鋭意検討した結

本発明に至った。[Means for Solving the Problems] As a result of intensive studies by the present inventors to solve the above problems, it has been found that it is effective to control specific physical property values of toner in a liquid developer containing a silicone solvent. I found out that
This led to the present invention.

あることを特徴とする静電写真用液体現像剤である。That is, the present invention provides an electrostatographic liquid developer comprising toner particles dispersed in a high-resistance dielectric carrier liquid containing at least a silicone solvent, (1) a solid content concentration of i.
o, the viscosity at 100°C at 0 wt% is 1 to 50
cp, (2) the elastic modulus of the dry solid after evaporating all the carrier liquid is 10' between 100 and 180°C;
(3) The critical surface tension of the dry solid is 18 to 36 dyne/(2).
本発明の液体現像剤は、担体液としてシリコーン系溶剤
