The authors have recently proposed a novel charge-control mechanism that assumes an appreciable temperature increase at the "toner/carrier" interface due to the triboelectrification. In this model, the temperature dependence of the electrical conductivity of charge-control agents (CCAs) plays the crucial role. Therefore, electrical and thermal properties of azo-metal complexes used as CCAs have been investigated in order to provide additional evidence for our model as well as to study their high thermal stability. The electrical conductivity of a typical azo-Fe complex (i.e., T-77 from Hodogaya Chemical) is found to increase exponentially with temperature, and the value around 100° C is about two to three orders of magnitude higher than that at room temperature. This supports our charge-control mechanism. On the other hand, the structure analyses of T-77, sodium salt of T-77, and sodium salt of a Cr-complex revealed that there are intermolecular hydrogen-bond networks or coordination networks, in which each cation bridges neighboring anions. This type of network is found to be responsible for high thermal stability above 250° C.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
