摘要： PURPOSE:To obtain a receptor with high sensitivity and low residual potential by adding a specified disazo compound to a receptor. CONSTITUTION:Disazo pigment represented by formula 1 (where A is an aromatic coupler, each of B1 and B2 is at least one of H, halogen, lower alkyl, OH and lower alkoxy, and B1 and B2 are identical with or different from each other) is dispersed in a charge transferring medium consisting of a charge transferring substance and an insulating binder, and a layer of the dispersion is formed on an electrically conductive layer. A charge generating layer contg. the disazo pigment and a charge transferring layer may be formed on the electrically conductive layer, and the disazo pigment may be added to a charge transfer complex. Thus, a receptor undergoing no reduction in the sensitivity and less increase in the residual charges even after repeated use is obtd.
摘要翻译：目的：通过向受体中加入特定的双偶氮化合物，获得具有高灵敏度和低残留潜能的受体。构成：由式1表示的双偶氮颜料（其中A是芳族成色剂，B1和B2各自为H，卤素，低级烷基，OH和低级烷氧基中的至少一种，B1和B2彼此相同或不同））分散在由电荷转移物质和绝缘粘合剂组成的电荷转移介质中，并且在导电层上形成分散体层。电荷产生层可以在导电层上形成双偶氮颜料和电荷转移层，并且可以将双偶氮颜料加入电荷转移络合物中。因此，即使在重复使用后，也不会降低灵敏度的降低和残留电荷的增加。
