摘要： An image forming apparatus of the invention includes a carrier solution application roller that rotates centering on a rotary shaft and applies a carrier solution to a transfer roller after an image of a liquid developer including toner and the carrier solution is transferred to a transfer medium, a transfer roller cleaning roller, supported by a cleaning member support portion through a rotary shaft, which removes toner remaining in the transfer roller, and a carrier solution application roller of which the amount of movement is larger than the amount of movement of the transfer roller cleaning roller when the cleaning member support portion is rotated. Even when the transfer roller moves, satisfactory cleaning properties are secured without breaking a mutual positional relationship by facilitating mutual positioning between the transfer roller and the transfer roller cleaning roller.

摘要： A non-magnetic single-component toner 8 of the present invention has toner mother particles 8a, and external additives 12 comprising: two hydrophobic silicas 13, 14 of which particle diameters are different from each other, i.e. a mean primary particle diameter of 7 nm to 12 nm and a mean primary particle diameter of 40 nm to 50 nm, and a hydrophobic rutile/anatase type titanium oxide 15 having a spindle shape of which major axial diameter is in a range from 0.02 nm to 0.10 nm and the ratio of the major axial diameter to the minor axial diameter is set to be 2 to 8, wherein the external additives 12 adhere to the toner mother particles 8a. By the hydrophobic silicas 13, 14 having work function smaller than the work function of the toner mother particles 8a, the negative charging property is imparted to the toner mother particles 8a and the fluidity is also insured. On the other hand, by mixing and using hydrophobic rutile/anatase type titanium oxide particles 15 having work function larger than or equal to the work function of the toner mother particles 8a together with the hydrophobic silicas 13, 14, the non-magnetic single-component toner 8 is prevented from excessively charged. Therefore, the amount of fog toner on non-image portions is reduced, the transfer efficiency is further improved, the charging property is further stabilized, and the production of reverse transfer toner is further inhibited.

摘要翻译：本发明的非磁性单组分调色剂8具有调色剂母粒子8a和外部添加剂12，其包含：两个粒径彼此不同的疏水性二氧化硅13,14，即平均一次粒径为7nm 平均一次粒径为40nm〜50nm的疏水性金红石/锐钛矿型氧化钛15，其主轴的直径为0.02nm〜0.10nm的主轴形状，相对于小轴向直径的主轴向直径设定为2至8，其中外部添加剂12粘附到调色剂母粒8a上。通过具有小于调色剂母粒子8a的功函数的功函数的疏水性二氧化硅13,14赋予调色剂母粒子8a的负带电性，还保证了流动性。另一方面，通过将功能大于或等于调色剂母粒8a的功函数的疏水性金红石/锐钛型氧化钛粒子15与疏水性二氧化硅13,14混合并使用，防止组分调色剂8过度充电。因此，非图像部分上的雾化调色剂的量减少，转印效率进一步提高，充电性能进一步稳定，并进一步抑制反转印调色剂的生产。
