    摘要： A process unit including a photoconductor unit having a photoconductor drum, a developing unit having a developing roller disposed in a development housing, and a support shaft means for supporting the developing unit pivotably relative to the photoconductor unit. The developing roller is disposed such that its surface is pressed against the surface of the photoconductor drum in a developing zone. The photoconductor drum and the developing roller are rotationally driven such that their respective surfaces move from below to above in the developing zone.

    摘要： According to the present invention, in the image forming apparatus in which so-called "cleaningless" is realized, no problems such as traces of paper powder, gray or foggy stripes and the like occur in a formed image. The image forming apparatus is provided with a brush for scratching toner remaining on the surface of the photosensitive drum and recovering paper powder adhering on the surface thereof. When the length of the brush extending from the root thereof to the photosensitive drum is taken as a�mm!, the length of the toughening member, toughening the brush materials, projecting from the root of the brush materials is taken as c�mm!, and the length of the portion of the brush, cutting into the photosensitive drum, is taken as b�mm!, the relationship among a�mm!, b�mm! and c�mm! satisfies the conditions that 0.3.ltoreq.(c/(a+b)).ltoreq.0.95, 0.1 �mm!.ltoreq.b.ltoreq.1.5 �mm!, and (a+b)

    摘要： An image-forming apparatus for forming image through the electric charging of a photosensitive material drum, exposure to light, developing and transfer, wherein a developing device also works to clean the toner remaining on the photosensitive material; an electric charge for effecting the electric charging has a scorotron charger located within .+-.45.degree. from a perpendicular downwardly drawn from the center of the photosensitive material drum, and has a hole on the side opposite to the opening for charging; and an electric field E.sub.1 between a wire and a grid in the scorotron charger is set to be stronger than an electric field E.sub.2 between the wire and a shield. The invention is further concerned with an image-forming unit used in the image-forming apparatus for forming image wherein said image-forming unit includes a photosensitive material drum having a photosensitive layer of an organic material, a first frame for supporting the photosensitive material drum maintaining the freedom of rotation, a photosensitive material unit having a scorotron charger which is provided on the first frame so as to be positioned within .+-.45.degree. from a perpendicular downwardly drawn from the center of the photosensitive material drum and has a ventilation hole on the side opposite to the opening for charging, a developing device, and a second frame which supports the developing device and also works as a toner container; wherein the first frame and the second frame have a common fulcrum and a resiliently engaging device on the side opposite to the fulcrum, and an electric field E.sub.1 between a wire and a grid in the scorotron charger is set to be stronger than an electric field E.sub.2 between the wire and a shield.
