成像装置、电子照相感光体及处理盒
摘要：
本发明涉及成像装置和在成像装置中使用的电子照相感光体及处理盒。成像装置包括：电子照相感光体；充电单元；潜像形成单元；显影单元；转印单元；以及清洁单元。成像装置满足如下条件中的至少一者：1)电子照相感光体的最外层包含有含四氟乙烯的颗粒，该含四氟乙烯的颗粒含有具有衍生自四氟乙烯的结构单元的聚合物；2)显影剂包含有含四氟乙烯的颗粒，该含四氟乙烯的颗粒含有具有衍生自四氟乙烯的结构单元的聚合物；3)成像装置还包括供给单元，该供给单元将含四氟乙烯的颗粒供给至所述电子照相感光体表面，其中含四氟乙烯的颗粒含有具有衍生自四氟乙烯的结构单元的聚合物。在成像装置中，图像密度降低的带状区域的形成得以有效抑制。
摘要（英）：

An image-forming apparatus includes an electrophotographic photoreceptor including an outermost layer having a crosslinked structure formed by dehydration condensation of a charge transport monomer containing a hydroxyl group and a developing unit that develops an electrostatic latent image on a surface of the electrophotographic photoreceptor with a developer containing a toner manufactured by dispersing particles for forming the toner in a solvent containing water and aggregating and heating the particles to form a toner image. The apparatus satisfies at least one of the following conditions: (1) the outermost layer of the electrophotographic photoreceptor contains tetrafluoroethylene-containing particles containing a polymer having structural units derived from tetrafluoroethylene; (2) the developer contains tetrafluoroethylene-containing particles containing a polymer having structural units derived from tetrafluoroethylene; and (3) the apparatus further includes a supply unit that supplies tetrafluoroethylene-containing particles containing a polymer having structural units derived from tetrafluoroethylene to the surface of the electrophotographic photoreceptor.
