Abstract

In recent years, it is required that the toner can be fused at lower energy from the viewpoint of saving energy. As it has already been reported by Shirai et al, it is achieved good fusing ability by using amorphous polyester including crystalline polyester (C-PES). It is supposed that the good fusing ability is due to drastic change of elasticity of C-PES around melting point.On the other hand, the toner including C-PES showed the poor storage stability. As it has already been reported by Fukuri et al in NIP23, the storage stability could be improved by anneal treatment. It was considered that the crystallization of C-PES was promoted and the crystallinity of the toner could be improved by anneal treatment, resulting in the improvement of the storage stability.In this study, it is investigated the crystallization mechanism of the toner including C-PES in anneal treatment. It is found that crystals are dispersed with nano-size in the toner by AFM observation. Furthermore, it is found that by nano dispersion of C-PES, the toner that satisfied the low energy fusing, the storage stability, and the durability can be obtained.
