    摘要: An image forming apparatus including an image forming unit, a fixing device, and circuitry is provided. The image forming unit is configured to perform a special image forming operation that forms a color toner image and a special toner image with a color toner and a special toner, respectively, on a recording medium and a normal image forming operation that forms the color toner image without forming the special toner image on the recording medium. The fixing device is configured to fix the color toner image and the special toner image on the recording medium. The circuitry is configured to perform, in the special image forming operation, a toner amount suppression control that makes an amount of the color toner on the recording medium per unit area smaller than that in the normal image forming operation.

    摘要: An electrophotographic photosensitive member has a surface layer that contains a urea compound having two or more urea moieties. Each of the urea moieties has a carbonyl group and two nitrogen atoms. Each of the two nitrogen atoms connects to an alkyl group and a substituted or unsubstituted aryl group or a substituted or unsubstituted arylene group.
