    • A transfer unit includes: an intermediate transfer belt that (i) holds a toner image that has been transferred from a photoreceptor drum and (ii) moves a surface holding the toner image; and a secondary transfer belt that comes into contact with the intermediate transfer belt. The transfer unit (i) transfers the toner image from the intermediate transfer belt to a sheet conveyed to the secondary transfer part and (ii) includes a cleaning unit that removes and collects toner from the surface of the intermediate transfer belt. The transfer unit also includes a power source for sequentially applying, to the secondary transfer belt, (i) a first voltage for generating an electric field that transfers normally-charged toner from the secondary transfer belt to the intermediate transfer belt and (ii) a second voltage for generating an electric field that transfers oppositely-charged toner from the secondary transfer belt to the intermediate transfer belt.
    • 转印单元包括:中间转印带,其(i)保持已经从感光鼓转印的调色剂图像,和(ii)移动保持调色剂图像的表面; 以及与中间转印带接触的二次转印带。 转印单元(i)将调色剂图像从中间转印带传送到传送到二次转印部件的纸张,(ii)包括从中间转印带的表面去除和收集调色剂的清洁单元。 转印单元还包括一个电源,用于顺序地向二次转印带施加(i)第一电压,用于产生将正常充电的调色剂从二次转印带传送到中间转印带的电场,以及(ii) 用于产生将相反充电的调色剂从二次转印带传送到中间转印带的电场的第二电压。

    • A photosensitive resin composition according to the present invention includes at least a base resin component (A) and a (meth)acryls compound (B), wherein the base resin component (A) is any one of: a polyimide resin (A-1) having at least either a hydroxyl group or a carboxyl group in its structure; a polyamide resin (A-2) having at least either a hydroxyl group or a carboxyl group in its structure; and photosensitive imide(meth)acrylsiloxaneoligomer (A-3). On this account, it is possible to realize characteristics such as (1) realization and improvement of water system developing property, (2) improvement of utility as an imidized film, (3) improvement of post-curing property, and (4) simplification of manufacture of a print wiring substrate. Thus, the photosensitive resin composition can be favorably used particularly in a photosensitive dry film resin, a laminate using the same, a print wiring substrate using the same, and the like.
    • 根据本发明的感光性树脂组合物至少包含基础树脂成分(A)和(甲基)丙烯酸类化合物(B),其中,所述基础树脂成分(A)为:聚酰亚胺树脂(A-1 )在其结构中具有至少一个羟基或羧基; 在其结构中具有至少羟基或羧基的聚酰胺树脂(A-2) 和感光酰亚胺(甲基)丙烯酰基硅氧烷寡聚体(A-3)。 因此,可以实现(1)实现和改善水系发展性的特征,(2)提高作为酰亚胺化膜的效用,(3)后固化性的提高,(4)简化 制造印刷布线基板。 因此,感光性树脂组合物特别优选用于感光性干膜树脂,使用该感光性树脂组合物的层叠体,使用该感光性树脂组合物的印刷用布线基板等。
