Abstract: A developing device includes a developer container, a developing unit, a developer outlet and a replenishment developer inlet. The developer container contains a developer composed of a toner and a first carrier. The developing unit develops an electrostatic latent image on an image carrier using the developer. The developer outlet discharges the developer. The replenishment developer inlet supplies a replenishment developer to the developer container. The replenishment developer includes a second carrier. A ratio of a poured bulk density of the second carrier to a poured bulk density of the first carrier ranges from 1.05 to 1.65.

Abstract: A precoat liquid used in an intermediate-transfer image forming method in which an actinic radiation-curable ink and an intermediate transfer member are used, the precoat liquid being applied onto a surface of the intermediate transfer member before the actinic radiation-curable ink is applied onto the surface of the intermediate transfer member, includes a water-soluble organic solvent having two or more hydroxyl groups per molecule. The water-soluble organic solvent has a C value of more than 0.03, the C value being calculated using Expression (1).

Abstract: A plurality of image parts, each having a different gloss level, are formed on the same recording material by electrophotographic technology. The plurality of gloss levels are visually recognized due to the plurality of image parts. The image forming method includes: developing electrostatic latent images on respective image carriers using a high softening point clear toner and a low softening point clear toner, to form a toner image by the high softening point clear toner and a toner image by the low softening point clear toner; transferring the toner images onto a recording material; and heat-fixing the toner image for low gloss and the toner image for high gloss transferred and formed onto the recording material, wherein a softening point Tm(a) of the high softening point clear toner and a softening point Tm(b) of the low softening point clear toner satisfy Tm(a)−Tm(b)>6° C.
