    • In the intermediate transfer belt of the present invention, a toner image formed on a plurality of photoreceptors is transferred and temporarily retained. The intermediate transfer belt comprises a reinforcing layer to reinforce the intermediate transfer belt and a surface protection layer that is stacked on the reinforcing layer through a middle layer and contacts the photoreceptors. The reinforcing layer and the surface protection layer have a larger value of surface resistance than a value of volume resistance of the whole belt. This makes it possible to prevent electric charge (voltage) from flowing out to rollers and image forming units and put proper electric charge (voltage) on the intermediate transfer belt. Preferably, the values of surface resistance of the reinforcing layer and the surface protection layer are 1×1010 to 1×1014 Ω/□ and the value of volume resistance of the whole intermediate transfer belt is less than 1×1010 Ω·cm.
    • 在本发明的中间转印带中,形成在多个感光体上的调色剂图像被转印并暂时保留。 中间转印带包括用于加强中间转印带的增强层和通过中间层堆叠在增强层上并与感光体接触的表面保护层。 增强层和表面保护层的表面电阻值大于整个带的体积电阻值。 这使得可以防止电荷(电压)流出到辊和图像形成单元并且在中间转印带上施加适当的电荷(电压)。 优选地,增强层和表面保护层的表面电阻值为1×10 10至1×10 14Ω/□,整个中间转印带的体积电阻值小于1×10 10Ω·cm。

    • A cleaning unit includes a traveling belt and a belt cleaning member. The traveling belt is formed in a loop and travels via the vicinity of the contact point between an image support member and an image support member cleaning member, and comes into contact with liquid developer stored in the cleaning unit. The belt cleaning member is in contact with the traveling belt and arranged in a position downstream of the contact point between the traveling belt and liquid developer stored in the cleaning unit, and upstream of the point at which the traveling belt passes the vicinity of the contact point between the image support member and the image support member cleaning member in the traveling direction of the traveling belt. The belt cleaning member is configured to remove liquid developer attached to the traveling belt.
    • 清洁单元包括行进皮带和皮带清洁部件。 移动带形成为环状,并经由图像支撑构件和图像支撑构件清洁构件之间的接触点附近行进,并与存储在清洁单元中的液体显影剂接触。 皮带清洁部件与行进皮带接触并且布置在运送皮带和存储在清洁单元中的液体显影剂之间的接触点的下游位置,并且行进皮带通过接触附近的点的上游 在图像支撑构件和图像支撑构件清洁构件之间沿行进带的行进方向。 皮带清洁部件被构造成去除附着在行进皮带上的液体显影剂。
