〔発明が解決しようとする課題〕
しかしながら、上に述べた従来のカートリッジ構成には
次のような問題かある。[Problems to be Solved by the Invention] However, the conventional cartridge configuration described above has the following problems.
まず、図のカートリッジ構成では、カートリッジに組み
込まれる主要構成要素か像担持体１の周囲で、記録紙Ｐ
の給送路の上側にのみ配置されている。即ち、帯電器２
、現像器３ｂ１ トナーボックス３ｃ、クリーナ４は像
担持体ｌの周囲のうち記録紙Ｐの給送路の上側にのみ集
中している。下側にあるのは転写器８と分離電極２２で
ある。このため、各構成要素の寸法には制約があるが、
それは工夫するとしても、トナーボックスだけは貯蔵量
を多くしようとすると容積を大きくせざるを得す、形状
のバランスを考慮すると横幅が大きくなるという問題が
ある。First, in the cartridge configuration shown in the figure, the recording paper P
It is placed only above the feed path. That is, charger 2
, the developing device 3b1, the toner box 3c, and the cleaner 4 are concentrated only above the feeding path of the recording paper P out of the periphery of the image carrier l. At the bottom are the transfer device 8 and the separation electrode 22. For this reason, there are restrictions on the dimensions of each component, but
Even if we try to do this, if we try to increase the storage capacity of the toner box, we have to increase the volume, and when we consider the balance of the shape, the width becomes large.
第２の問題は、記録紙の給送路が像担持体１の下側にな
っているために像担持体１上のトナー画像は記録紙Ｐの
上側の面に転写される。これをそのまま、定着ローラで
定着して排出すると画像面は上を向いていることになる
。そうするとプリンター等で１頁目かも順に複数頁分を
プリントアウトすると１頁目が一番下、即ち、頁順が逆
になって積み重ねられることになる。しかし、これでは
あらためて頁の揃え直しをしなければならず手間がかか
るので、これを避けるために定着し終わった記録紙を１
回折り返し反転させる構成が必要になる。The second problem is that since the recording paper feeding path is below the image carrier 1, the toner image on the image carrier 1 is transferred to the upper surface of the recording paper P. If this is fixed with a fixing roller and ejected, the image surface will be facing upward. In this case, if a printer or the like prints out a plurality of pages in order, including the first page, the first page will be at the bottom, that is, the pages will be stacked in reverse order. However, this requires a lot of time and effort as the pages must be rearranged again, so to avoid this, it is necessary to
A configuration that folds back and inverts is required.
第３に、記録紙の給送路が露呈できないため給送路の清
掃や紙づまりの処置にやや難がある。Third, since the recording paper feeding path cannot be exposed, it is somewhat difficult to clean the feeding path and deal with paper jams.

を起したときは、その処理が容易でないという問題があ
った。Furthermore, in image forming apparatuses such as facsimile machines and printers with scanners that are equipped with a reading unit that reads images of originals, the original is transported to the reading unit, and after the image has been read, the original is ejected from the device. In an image forming apparatus that requires an original transport path in addition to the above-mentioned recording paper transport path, the apparatus is large and it is not easy to deal with a failure in transport of the original or recording paper. There was a problem.
本発明は、上記問題を解決し、原稿や記録紙の搬送路か
露呈できる構成で、トナーボックスや現像器等が着脱可
