反相气相色谱法（IGC）已被应用于研究显影剂材料的表面性质，测量酸，碱和分散体的相互作用。制备模型载体和调色剂颗粒，其中调色剂与各种纳米颗粒金属氧化物表面添加剂：二氧化硅、二氧化钛和氧化铝共混。用这些表面添加剂制剂测定调色剂充电。IGC用于表征载体和添加剂表面化学。从IGC的结果进行了评价方面的调色剂电荷和金属氧化物的功函数。的相关性被发现之间的IGC确定的表面酸碱相互作用参数的显影剂材料，和它们的功函数和摩擦电荷。IGC、功函数和充电结果一起强烈支持用于显影剂充电的功函数模型，其中功函数由显影剂组分的酸和碱性质确定。因此，随着金属氧化物表面添加剂的酸与碱相互作用参数的比率增加，调色剂电荷变得更负。计算结果与本系列配套论文中提出的表面态荷电模型定量一致。
Inverse gas chromatography (IGC) has been applied to study the surface properties of developer materials, measuring acid, base, and dispersion interactions. Model carrier and toner particles were prepared, where the toner was blended with various nanoparticulate metal oxide surface additives: Silica, titania, and alumina. Toner charging was determined with these surface additive formulations. IGC was used to characterize carrier and additive surface chemistry. Results from IGC were evaluated with respect to toner charge and to metal oxide work functions. A correlation was found between IGC-determined surface acid-base interaction parameters of the developer materials, and their work functions and triboelectric charge. Together, the IGC, work function, and charging results strongly support a work function model for developer charging, where the work function is determined by the acid and base properties of the developer components. Thus, as the ratio of the acid to base interaction parameters of the metal oxide surface additive increased, toner charge became more negative. The results are in quantitative agreement with the surface states charging model proposed in the companion paper in this series.
