Description
【発明の詳細な説明】 （Ａｔ 発明の技術分野 ４４する印刷装置に関する。[Detailed description of the invention] (At Technical field of invention 44 printing apparatus.
０３） 技的の背景
近年、電子写真装置等のいわゆるノンインパクト型の印

頻繁に使用されるようになってお夛、装置の信頼性は極
めて為いものが要求されている。03) Technical background In recent years, so-called non-impact printing devices such as electrophotographic devices have been frequently used in offices, etc. due to their high speed and noiselessness. Extremely high reliability is required.
（Ｃ） 従来技術と問題点
第１図は、従来において、一般によく用いられている電
子写真装置の概略囚である。(C) Prior Art and Problems FIG. 1 is a schematic diagram of an electrophotographic apparatus commonly used in the past.
図において、感光ドラムｌは帯電器２により均一に全面
帯電され、次に、嬉光部３によ多画像情報が露光される
。In the figure, a photosensitive drum 1 is uniformly charged over its entire surface by a charger 2, and then a photosensitive area 3 is exposed to multiple image information.
感光ドラム１の露光された部分は表面電位が下がるので

紙６上に転与された現像粉像は定着部７によル定着され
、印刷物として仕上げられる。Since the surface potential of the exposed portion of the photosensitive drum 1 decreases, the original image information is converted into an electrostatic pattern. The electrostatic pattern on the photosensitive drum 1 is developed in the developing section 4 by supplying developer powder, and becomes a developer powder image. The developer powder image on the photosensitive drum 1 is transferred onto a sheet of paper 6 in a transfer section 5 . The developer powder image transferred onto the paper 6 is fixed by the fixing section 7 and finished as a printed matter.
転写後、感光ドラムｌ上に残留する現像粉はクリーニン
グブラシ８により完全に除去される。After the transfer, the developer powder remaining on the photosensitive drum 1 is completely removed by the cleaning brush 8.

挾まシ圧力が像に加えられなかった場合等に生ずる。Printing is performed by sequentially repeating the steps described above. However, when such a developer powder image is
The printing device that performs the process of forming and fixing a developing powder image does not adhere to the paper 6 as it is. Use difficult-to-use developing powder. Therefore, if the fixing mechanism in the fixing section 7 becomes incomplete, a problem occurs in that the developer powder image is not fixed on the paper 6. This problem can occur, for example, in the case of a heating fixing mechanism that uses heat, when the heating temperature is low, or when the pressure foot fI! In the case of a mechanism, this occurs when a foreign object is pinched and no pressure is applied to the image.
そして、この障害は、現像粉像が転写された用紙を見た

るため、手や衣服が汚れるという障害が起る。This fault is recorded correctly and is not detected as a fault just by looking at the paper to which the developing powder image has been transferred. Therefore, when using paper with an unfixed developer powder image, when transporting the paper or turning the pages, the paper will be removed and the developer powder image will disappear, and the developer powder will be smeared with black powder, so you will not be able to handle it by hand. Problems arise in that clothes get dirty.

定着であることが検出されないと多責の用紙が無駄にな
るという欠点を有する。In addition, the above-mentioned type of printing IT uses continuous paper, and several thousand sheets of paper can be printed per minute. Therefore, this printer's printing apparatus has the disadvantage that unless it is detected that the developing powder image transferred onto the paper 6 is unfixed, the paper is wasted.
（２）発明の目的
本発明の目的は、前述の欠点に鑑みてなされたものであ

、また、印刷装置の信頼性を向上できる。First, the developer powder image transferred onto the paper 6 is expanded by the fixing device 7. Here, the sliding roller 9 does not rotate at all times, but is rotated by the rotation mechanism 10 during busy periods, for example, every time one additional page of paper 6 is added. The developing powder image on paper 6 is
If the fixing device 7 fixes the image well on the paper 6,
No developing powder adheres to the sliding p-29, and the detection means 11 does not detect it. Developing powder adheres to the sliding part p--)9, and the detecting means 11 detects that fixing is not performed well. ・Developing powder adhering to the sliding part p--29 is detected, and the detecting means 11 detects that the fixing is not performed well. A stop signal is output to a host device (not shown) to stop the printing device.According to the present invention, since the fixing state of the developer powder image fixed on the paper 6 can be detected, it is possible to It is possible to avoid waste of paper when the developing powder image on the paper 6 is in an unfixed state, and it is also possible to improve the reliability of the printing device.
