    摘要： A transferring device in which a transfer roller having a diameter which is not less than 60% of the diameter of an organic photosensitive drum with a diameter of 10 to 20 mm is arranged with a clearance provided between the transfer roller and the organic photosensitive drum. The transferring device avoids problems such as current leakage and reverse transfer of toner in the case of miniaturization of an image forming apparatus or contamination of the transfer roller, and easily sets a transfer current because an effective transfer current width is large.

    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： 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.

    摘要： A transfer roller which transfers a toner image to a recording sheet fed in a gap between a photoreceptor drum and the transfer roller, and a pre-transfer guide which guides the recording sheet are pushed to be displaceable by a spring by use of a roller so that a predetermined gap is maintained between the photoreceptor drum and the transfer roller and that the positions of the transfer roller and the pre-transfer guide depend on the position of the photoreceptor drum. The recording sheet P on which an image has been transferred is conveyed to a conveying guide. A post-transfer guide which receives the abutment of the end of the image transferred recording sheet and guides the recording sheet to the conveying guide is provided to be displaceable integrally with the transfer roller and the pre-transfer guide. The post-transfer guide is made of a resin with a resistance of 10.sup.10 .OMEGA. to 10.sup.16 .OMEGA..
