    • A laminate (6) is prepared by superposing a fibrous web (1a), (1b) containing fibers comprising polyethylene terephthalate on one side or both sides of a net-form sheet (4); water needling the fibrous web (1a), (1b) to entangle the fibers of the fibrous web (1a), (1b) with each other, and also to entangle the fibers of the fibrous web (1a), (1b) with the net-form sheet (4); and then, blowing hot air having a temperature above the glass transition temperature (Tg (° C.)) of the polyethylene terephthalate and below “Tg (° C.)+70° C.” to the laminate (6) by through-air technique. Preferably, after preparing the laminate (6) by entangling the fibers of the fibrous web(s) (1a), (1b) with the net-form sheet (4), the laminate (6) is dried with hot air; and then hot air is blown to the laminate (6) by through-air technique.
    • 通过将包含聚对苯二甲酸乙二醇酯的纤维的纤维网(1a)(1b)叠置在网状片材(4)的一侧或两侧上来制备层压体(6); 水针刺纤维网(1a),(1b)使纤维网(1a),(1b)的纤维彼此缠结,并使纤维网(1a),(1b)的纤维与 网格表(4); 然后吹入温度高于聚对苯二甲酸乙二醇酯的玻璃化转变温度(Tg(℃))的温度并低于“Tg(℃)+ 70℃”的热空气。 通过空气技术到层压板(6)。 优选地,通过将​​纤维网(1a),(1b)的纤维与网状片(4)缠结来制备层压体(6)之后,用热空气干燥层压体(6) 然后通过空气技术将热空气吹送到层压板(6)。

    • A cleaning sheet (1) includes at least one continuous-filament aggregate (10) formed by aggregating and orienting a multitude of continuous filaments (11) substantially in one orientation direction. The continuous filaments (11) are joined by a single first joining line (12) extending continuously in a direction orthogonal to the orientation direction of the continuous filaments (11) and are joined by a plurality of second joining lines (13) extending in the orientation direction. In this way, the continuous filaments (11) in the continuous-filament aggregate (10) are kept in an aggregated state. Preferably, the second joining lines (13) are connected to the first joining line (12).
    • 清洁片(1)包括至少一个通过基本上沿一个取向方向聚集和定向多根连续长丝(11)而形成的连续长丝聚集体(10)。 连续长丝(11)通过在与连续长丝(11)的取向方向正交的方向上连续延伸的单个第一接合线(12)连接,并且通过在第二接合线(13)中延伸的多个第二接合线 定位方向。 以这种方式,连续细丝聚集体(10)中的连续细丝(11)保持聚集状态。 优选地,第二接合线(13)连接到第一接合线(12)。

    • The development device includes a developer storage part storing a developer, a developer carrier having a carrying surface for carrying the developer and a first magnet, and receiving the developer from the developer storage part on the carrying surface while rotating in a predetermined direction, and supplying the developer to a predetermined image carrier, a magnetic member formed from a magnetic material, forming a predetermined regulatory gap with the carrying surface, and arranged opposite to the first magnet, a second magnet disposed more upstream than the magnetic member when viewed from the rotating direction of the developer carrier, and having a magnetic pole of the same polarity as the first magnet, and a deterioration suppressing part suppressing deterioration of the developer transported to the regulatory gap along with the rotation of the developer carrier.
    • 显影装置包括存储显影剂的显影剂存储部分,具有用于承载显影剂的承载表面的显影剂载体和第一磁体,并且在沿预定方向旋转的同时从显影剂存储部分在显影剂储存部分上接收显影剂, 显影剂到预定的图像载体,由磁性材料形成的磁性构件,与承载表面形成预定的调节间隙,并且与第一磁体相对布置;第二磁体,当从旋转的 显影剂载体的方向,并且具有与第一磁体相同极性的磁极,以及劣化抑制部,抑制传送到调节间隙的显影剂的劣化以及显影剂载体的旋转。
