Description
【請求項５】 樹脂被覆層が更に導電性微粒子を含有することを特徴とする請求項１乃至４のいずれかに記載の摩擦帯電付与部材。 5. The triboelectric charging member according to claim 1, wherein the resin coating layer further contains conductive fine particles.
【請求項９】 現像容器と、現像容器内に保持されたトナーを有する現像剤を担持して潜像保持体と対向する現像部へと該現像剤を搬送する現像剤担持体を有し、潜像保持体上の潜像を該現像剤担持体により担持搬送された現像剤の摩擦帯電付与部材との摩擦により帯電されているトナーにより現像し可視像化する現像装置において、
該摩擦帯電付与部材の少なくともトナーと接触する表面は、（１）結着樹脂、（２）鉄粉に対して正帯電性である第４級アンモニウム塩化合物、及び（３）含窒素複素環化合物を少なくとも有する樹脂組成物によって形成された樹脂被覆層を有することを特徴とする現像装置。
9. comprises a developing container, a developer carrying member for conveying to the developing unit facing the developer carrying the latent image holding member having the retained toner to the developing container a developer, In a developing apparatus that develops a latent image on a latent image holder with toner charged by friction with a friction charging member of the developer carried and conveyed by the developing agent carrier and visualizes it.
At least the surface of the triboelectric charging member in contact with the toner is (1) a binder resin, (2) a quaternary ammonium salt compound that is positively charged with respect to iron powder, and (3) a nitrogen-containing heterocyclic compound. A developing apparatus having a resin coating layer formed of a resin composition having at least.
【請求項１３】 樹脂被覆層が更に導電性微粒子を含有することを特徴とする請求項９乃至１２のいずれかに記載の現像装置。 13. The developing apparatus according to claim 9, wherein the resin coating layer further contains conductive fine particles.
また、樹脂被覆層中に更に導電性微粒子を含有していることも良い。 Further, it is also preferable that the resin coating layer further contains conductive fine particles.
また、上記目的は、現像容器と、現像容器内に保持された現像剤を担持して潜像保持体と対向する現像部へと該現像剤を搬送する現像剤担持体を有し、潜像保持体上の潜像を該現像剤担持体により担持搬送された現像剤により現像し可視像化する現像装置において、上記の摩擦帯電付与部材の少なくともいずれかひとつを有する現像装置により達成される。 Further, the above object has a developing container and a developing agent carrier that carries the developing agent held in the developing container and conveys the developing agent to a developing unit facing the latent image holder, and has a latent image. This is achieved by a developing device having at least one of the above friction charging members in a developing device that develops a latent image on a holding body with a developing agent carried and conveyed by the developing agent carrier and visualizes it. ..
