摘要： The present invention relates to a process for producing a toner for electrophotography which is capable of suppressing liberation of a wax from a resin binder and exposure of the wax to a surface of respective toner particles in the step of obtaining fused particles upon production of the toner, and reducing a content of fine powders in the toner, and which is characterized by an excellent low-temperature fusing property and an excellent anti-high-temperature offset property. The process for producing a toner for electrophotography according to the present invention includes the following steps 1 to 3: Step 1 of mixing and emulsifying a wax, a resin emulsion containing a resin having an acid value of from 10 to 300 mgKOH/g, and an oxazoline group-containing polymer with each other to obtain a water dispersion of releasing agent particles; Step 2 of mixing and aggregating the water dispersion of the releasing agent particles obtained in the step 1 with a water dispersion of resin particles containing a carboxyl group-containing resin binder to obtain aggregated particles; and Step 3 of fusing the aggregated particles obtained in the step 2 to obtain fused particles.
摘要翻译： 本发明涉及一种电子照相用调色剂的制造方法，该方法能够抑制蜡从树脂粘合剂中的脱离，并且在生产调色剂时获得熔融颗粒的步骤中将蜡暴露于各调色剂颗粒的表面 ，并且减少调色剂中细粉末的含量，其特征在于优异的低温熔融性能和优异的抗高温偏移性能。 本发明的电子照相用调色剂的制造方法包括以下步骤1〜3：将蜡混合乳化的工序1，含有酸值为10〜300mgKOH / g的树脂的树脂乳液，以及 含有恶唑啉基的聚合物以获得脱模剂颗粒的水分散体; 将步骤1中获得的脱模剂颗粒的水分散体与包含含羧基的树脂粘合剂的树脂颗粒的水分散体混合并聚集以获得凝集颗粒的步骤2; 和将步骤2中获得的凝集颗粒熔合的步骤3，得到熔融颗粒。

摘要： A warming device (1) includes a heat generating element (3) that contains a powder of an oxidizable metal (3a), a powder of a carbon material (3b), and a powder of a porous material (3c) other than the oxidizable metal (3a) and the carbon material (3b). The heat generating element (3) is a sheet material. It is preferable that, in the heat generating element (3), the ratio of the mass content of water to the mass content of the powder of the oxidizable metal (3a) multiplied by one hundred is from 30 to 270. It is preferable that, in the heat generating element (3), the ratio of the mass content of the porous material (3c) to the mass content of oxidizable metal (3a) multiplied by one hundred is from 1 to 30. It is preferable that, in the heat generating element (3), the ratio of the mass content of the porous material (3c) to the mass content of water multiplied by one hundred is from 1 to 30.
