摘要： An image forming apparatus includes a plurality of image carriers and a transfer assembly. The transfer assembly includes a plurality of transferees, a supporter, and a plurality of transferee holders. The plurality of transferers is each configured to electrostatically transfer a toner image carried on one of the image carriers onto an intermediate transfer member or a recording medium. The supporter is configured to support the transferers. The transferer holders are each configured to hold one of the transferers. Each of the transferee holders and the transferer held thereby form an integrated individual unit independently attachable to and detachable from the supporter.

摘要： An image forming apparatus includes an image carrier, a transferor, a fixing unit, and a guide. The image carrier carries a toner image. The transferor opposes the image carrier to form a transfer nip and transfers the toner image on the image carrier onto a recording medium at the transfer nip. The fixing unit fixes the toner image on the recording medium. The guide guides the recording medium bearing the toner image from the transferor toward the fixing unit and includes a surface portion directly contacting the recording medium. The surface portion includes a material for charging the recording medium to have a polarity opposite to the polarity of a toner forming the toner image.

摘要： A developing device includes a developer bearer to carry, by rotation, developer including toner and magnetic carrier to a developing range facing a latent image bearer; a casing including a developer container and an opening to expose a part of the developer bearer disposed in the casing; an opposing face of the casing including a conductive material and opposing to a surface of the developer bearer downstream from the developing range in a direction of rotation of the developer bearer; a developing bias source to apply a developing bias to the developer bearer; and an insulation layer disposed on the opposing face of the casing. The opposing face is disposed across, from the developer bearer, a casing gap sized to allow the developer borne on the developer bearer to contact the opposing face.
