发明名称 Image forming apparatus for improving transfer efficiency and preventing image deterioration
摘要 An image forming apparatus including multiple colored toner image forming units to form multiple colored toner images on a rotatable body, a transfer device to collectively transfer the multiple colored toner images onto a recording medium from the rotatable body, a fixing device to fix the multiple colored toner images onto the recording medium, and a light-colored toner image forming unit to form a light-colored toner image as a bottommost layer of a resultant full-color toner image formed on the rotatable body. The multiple colored toner images are sequentially superimposed on the light-colored toner image formed as the bottommost layer of the resultant full-color toner image formed on the rotatable body. A condition for forming the light-colored toner image by the light-colored toner image forming unit is set such that the light-colored toner image is not transferred onto the recording medium from the rotatable body by the transfer device.
