Summary:To provide a unit that suppresses a transfer failure of a toner image formed with a flat toner.SOLUTION: A unit comprises: a developing device that stores a developer having a flat toner including a flat pigment and develops an electrostatic charge image formed on a surface of an image holding body with the developer as a toner image; and a transfer device that has an intermediate transfer belt including a resin and conductive carbon particles, in which when the flat toner is attached to an outer peripheral surface and subsequently air is blown to the outer peripheral surface from an upper side of the outer peripheral surface while increasing a blowing pressure, within a blowing pressure of 25 kPa, whole flat toner attached to the outer peripheral surface is separated from the outer peripheral surface.SELECTED DRAWING: Figure 1 【課題】扁平トナーによるトナー像の転写不良が抑制されるユニットの提供。【解決手段】扁平顔料を含む扁平トナーを有する現像剤を収容し、前記現像剤により、像保持体の表面に形成された静電荷像をトナー像として現像する現像装置と、樹脂及び導電性カーボン粒子を含み、外周面に扁平トナーを付着させた後、外周面上方側から、吹き付け圧力を上昇させながら、外周面に空気を吹き付けたとき、吹き付け圧力が２５ｋＰａ以内で、外周面に付着した全ての扁平トナーが外周面から離間する中間転写ベルトを有する転写装置と、を備えるユニット。【選択図】図１
