摘要： A developing device to develop a latent image on a rotatable image bearer includes an upstream developing roller disposed opposite the image bearer at a first developing position, and a downstream developing roller disposed adjacent to and downstream from the upstream developing roller in a direction of rotation of the image bearer, disposed opposite the image bearer at a second developing position. Each of the upstream developing roller and the downstream developing roller has a most approachable surface that approaches closest to the image bearer and a most withdrawn surface that withdraws farthest from the image bearer. In a state in which a reference surface point of the image bearer is disposed opposite the most approachable surface of the upstream developing roller at the first developing position, the reference surface point opposes the most withdrawn surface of the downstream developing roller at the second developing position.

摘要： An image forming apparatus has an endless belt which serves as an image carrier is characterized by reduced image misregistration and reduced machining cost. When the endless belt feed path is divided into a path from a drive roller to a tension roller, and a path from the tension roller to the drive roller, the eccentricity of an idle roller located on the path on the side including a latent image forming point is set to a value smaller than that of an idle roller located on the path not including the image forming point.

摘要： In an image forming apparatus, attachment/detachment guide pins (10 and 11) are disposed on a side face of a belt cartridge (12). Attachment/detachment guide grooves (30, 31, and 32) which guide the attachment/detachment guide pins (10 and 11) are disposed in a frame (29) of a main unit of an image forming apparatus. A belt tension applying mechanism including a tension link (13) and a spring (15) is disposed on the side of the apparatus main unit. When the belt cartridge (12) is to be attached to the apparatus main unit, the cartridge is attached along the attachment/detachment guide grooves (30, 31, and 32), so that the rotation shaft of a tension roller (4) is easily and surely engaged with the belt tension applying mechanism (13 and 15).

摘要： A transport roll 1 consists of a metal roll 3 of 40 mm in diameter covered with a conductive PFA tube 2 of 10.sup.10 .OMEGA.cm in volume resistivity and 200 .mu.m in thickness. A DC voltage source 4 is connected to the metal roll. A sheet of paper 5 bearing toner images 6 and 7 on both sides thereof receives a drive force from a paper drive roll, and turns with the movement of the paper. The DC voltage source produces voltage VB1 of the same polarity as the charging polarity (positive) of the toner image 6 being in contact with the transport roll. The voltage VB1 is optimumly controlled so as to prevent the transport roll from being soiled with toner.

摘要： In a multi-stage roll magnetic brush type of developing device, at least two opposite direction rotation rolls which rotate in an opposite rotation direction to that of a photosensitive body are arranged adjacently and oppositely to a photosensitive body, and at least one same direction rotation developing roll which rotates in the same rotation direction as that of the photosensitive body is arranged adjacently, oppositely to the photosensitive body and upstream of the opposite direction rotation developing rolls in the rotation direction of the photosensitive body. Thus, the path of carrying the developer by the same direction rotation developing roll and the opposite direction rotation developing rolls can be optimized. In the wide area printing at high speed, an image with stabilized printing quality can be obtained without an increase in the production cost.

摘要： Each of a charging process on and after a second time is carried out by a charging means having a controlling electrode. The relationship between a controlling potential (Vg) applied to the controlling electrode of each charming means, the target surface potential (Vo) of a non-image portion of a surface of a photosensitive body and the direct current component potential (Vdc) of a developing bias potential in each developing process is satisfied by the formula, which is .vertline.Vo.vertline.>.vertline.Vdc.vertline..gtoreq..vertline.Vg.vertline.. Thereby the corona current ia supplied to flow sufficiently, it can rise the surface potential of a toner image portion of the surface of the photosensitive body after the re-charming without the excessive rise of the surface potential of the non-image portion of the photosensitive body. The surface potential of the toner image portion of the photosensitive body after the re-charging becomes to higher than the direct component potential (Vdc) of the developing bias potential, it can prevent from mixing the toners having other color.
