摘要： An image forming apparatus including a latent image bearing member, a charger, a latent image forming device, a developing device, and a transfer device is provided. The transfer device is adapted to transfer a toner image formed on the latent image bearing member onto an intermediate transfer member or a recording medium by action of a transfer elected field in a transfer position where the latent image bearing member faces the transfer device. When a non-charged portion of the latent image bearing member that has not been charged to a predetermined potential by the charger passes through the transfer position, a strength of the transfer electric field is lowered than that in transferring the toner image.

摘要： An image forming apparatus is provided. The image forming apparatus includes a photoconductor, an irradiator, a developing device including a developing roller, a development bias applying device, a toner supplying roller and a supply bias applying device, and a controller. The controller changes supply bias offset by reference to at least one of five parameters including photoconductor travel distance, operation temperature of the developing device, operation humidity of the developing device, continuous operating time of the developing device, and color information of image to be produced. After changing the supply bias offset, the controller forms plural toner patterns for image density adjustment on the photoconductor by changing the development bias, and sets the development bias to a certain bias based on the image densities of the plural toner patterns so that the image produced by the developing device has a targeted image density.

摘要： A fixing device includes a nip formation pad disposed opposite an inner circumferential surface of an endless belt and a pressing rotary body pressed against the nip formation pad via the endless belt to form a fixing nip between the endless belt and the pressing rotary body, through which a recording medium is conveyed. The pressing rotary body has a diameter increasing from a center to each lateral end in an axial direction thereof. The nip formation pad includes a projection disposed downstream from a rotation axis of the pressing rotary body in a recording medium conveyance direction. The projection projects toward the pressing rotary body in an amount increasing from each lateral end to a center in a longitudinal direction of the nip formation pad parallel to the axial direction of the pressing rotary body.
