Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a toner for electrostatic latent image development that can suppress the occurrence of fogging even after continuous image formation.SOLUTION: A toner for electrostatic latent image development contains a plurality of toner particles 1. The toner particle 1 contains a toner base particle 2 and a plurality of external additive particles 3 provided on the surface of the toner base particle 2. The external additive particle 3 contains an external additive core 4 and a coating layer 5 that coats the external additive core 4. The coating layer 5 is a condensation polymer or a condensation copolymer of at least one of tetramethylmelamine tetramethylether, pentamethylmelamine pentamethylether, and hexamethylmelamine hexamethylether.SELECTED DRAWING: Figure 1
【課題】連続して画像を形成した場合であってもカブリの発生を抑制可能な静電潜像現像用トナーを提供する。【解決手段】静電潜像現像用トナーは、トナー粒子1を複数含む。トナー粒子1は、トナー母粒子2と、トナー母粒子2の表面に備えられる複数の外添剤粒子3とを有する。外添剤粒子3は、外添剤コア4と、外添剤コア4を被覆するコート層5とを有する。コート層5は、テトラメチロールメラミンテトラメチルエーテル、ペンタメチロールメラミンペンタメチルエーテル及びヘキサメチロールメラミンヘキサメチルエーテルのうちの少なくとも1種の縮合重合体又は縮合共重合体である。【選択図】図1 |
