PROBLEM TO BE SOLVED: To make it possible to cause a large-diameter external additive to be fastened to a toner surface even when the large-diameter external additive is processed at a processing temperature equal to or lower than the glass transition point (Tg) of a resin component contained in a toner, suppress a transition of the external additive to a member, and prevent the occurrence of image defects.SOLUTION: There is provided a processing device for toner processing a processing target object including toner particles and an external additive, the processing device for toner comprising: a cylindrical processing chamber that stores the processing target object; and a rotor that is rotatably provided inside the processing chamber with a drive shaft as the center, where the rotor has a specific shape and includes: a rotor body; and a plurality of processing parts including a processing surface that collides with the processing target object through the rotation of the rotor to process the processing target object.SELECTED DRAWING: Figure 1 【課題】トナーに含有される樹脂成分のガラス転移点（Ｔｇ）以下の処理温度において、大粒径外添剤を処理しても大粒径外添剤がトナー表面に固着され、部材への移行を抑制でき、画像不良を生じさせないようにする。【解決手段】トナー粒子と外添剤とを含む被処理物を処理するトナー用処理装置であって、前記トナー用処理装置が、前記被処理物を収容する円筒形の処理室と、前記処理室の内部で駆動軸を中心に回転可能に設けられた回転体と、を備え、前記回転体は、回転体本体と、前記回転体の回転により前記被処理物に衝突して前記被処理物を処理する処理面を有する複数の処理部と、を備え、特定の形状を有する。【選択図】図１
