〔産業上の利用分野〕
本発明はカールソンプロセスを用いた電子写真プリンタ
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electrophotographic printer using the Carlson process.
従来、この種のカールソンプロセスを用いた電子写真プ
リンタの電子写真プロセスは、帯電、露光、現像、転写
、定着、クリーニング、除電の各プロセスステップから
構成されていた。Conventionally, the electrophotographic process of an electrophotographic printer using this type of Carlson process has been comprised of process steps of charging, exposure, development, transfer, fixing, cleaning, and static elimination.
上述した従来の電子写真プリンタの電子写真プロセスは
最も基本的な構成であり、各プロセスステップのどれ１
つも欠くことができず、又、各々のプロセスステップが
独立して構成されているため、電気写真プリンタの構成
が複雑になり、ひいては小型化できないという欠点があ
った。The electrophotographic process of the conventional electrophotographic printer described above has the most basic configuration, and each process step
Moreover, since each process step is constructed independently, the construction of the electrophotographic printer becomes complicated, and furthermore, there is a drawback that miniaturization is impossible.
本発明の目的は前記課題を解決した電子写真プリンタを
提供することにある。An object of the present invention is to provide an electrophotographic printer that solves the above problems.
前記目的を達成するため、本発明はカールソンプロセス
を用いた電子写真プリンタにおいて、そのクリーニング
部に導電性ブレードを使用したブレードクリーニング機
構を有するものである。To achieve the above object, the present invention provides an electrophotographic printer using the Carlson process, which has a blade cleaning mechanism using a conductive blade in its cleaning section.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例を示す構成図である。FIG. 1 is a block diagram showing an embodiment of the present invention.
１は感光体、２は帯電部、３は露光部、４は現像部、５

ドクリーニング部、Ａは感光体の回転方向である。1 is a photoreceptor, 2 is a charging section, 3 is an exposure section, 4 is a developing section, 5
6 is a transfer section, 6 is a fixing section, 7 is a blade cleaning section whose blade is conductive, and A is the rotation direction of the photoreceptor.

１に付着したトナー９ａを物理的にかき落とすと同時に
、ブレード７ａが導電性を持っているため、導体７ｂを
通して感光体１表面の電荷８を消失させる。FIG. 2 is an enlarged view of the blade cleaning section 7 in FIG. 1. 1 is a photoreceptor, 7a is a conductive plate, 7b
8 is a conductor that grounds the conductive blade, 8 is a charge attached to the surface of the photoreceptor, 9a is toner attached to the surface of the photoreceptor, 9b
is the toner scraped off by the blade 7a, and A is the rotation direction of the photoreceptor. The conductive blade 7a is connected to the photoreceptor 1
Similar to the effect of conventional blades, the blade 7a physically scrapes off the toner 9a attached to the photoconductor 1 at the contact part, and at the same time, since the blade 7a has conductivity, the charge on the surface of the photoconductor 1 is removed through the conductor 7b. 8 disappears.
以上説明したように本発明は電子写真プリンタの電子写

電効果も有するため、従来独立して構成されていた除電
部が不必要となり、電子写真プリンタの構成が簡単にな
るという効果がある。As explained above, the present invention has a blade cleaning structure in which the blade is conductive in the cleaning section of the electrophotographic process of an electrophotographic printer, so that the cleaning section has a static elimination effect in addition to the conventional cleaning effect. Therefore, the static eliminator, which was conventionally configured independently, becomes unnecessary, and the configuration of the electrophotographic printer is simplified.
