摘要： A developing device includes a developer container; a developer carrier; a first transport member having a rotation shaft and a transport blade; a second transport member having a rotation shaft and a transport blade; a partition member; a guide member; a first inflow portion; a second inflow portion; and a movement portion. The rotation shaft of the first transport member is located within a projection area of the developer carrier projected from above. A second imaginary tangent line extending vertically and touching an outer end of the transport blade of the first transport member is farther from the image carrier than a first imaginary tangent line extending vertically and touching an outer surface of the developer carrier. A first distance between the first and second imaginary tangent lines is smaller than a second distance between a rotation center of the image carrier and an inner surface of the developer container.

摘要： An image forming apparatus includes image forming units, a transfer unit that transfers a superposed toner image including toner images formed by the image forming units onto a sheet, a fixing unit that fixes the superposed toner image onto the sheet, and a controller that performs control such that a toner image is formed while the amount of toner used per unit area by the second image forming unit when forming a line image is smaller than that when forming a solid image. The image forming units include a first image forming unit that forms a toner image that is transferred onto the transfer unit relatively earlier than the other toner images and a second image forming unit that forms a toner image that is transferred onto the transfer unit relatively later than the other toner images, the first and second image forming units using the same color toner.
