摘要： A benzimidazolone compound is disclosed which has a plurality of hues in a single structural formula and good dispersibility in a binder resin and thus is useful as a pigment. The benzimidazolone compound is further useful as a pigment since it suffers little aggregation even when two or more kinds of the compound having different hues are used at the same time for obtaining an aimed hue. The benzimidazolone compound is represented by the following general formula (1): (wherein R1, R2, R3 and R4 independently represent a hydrogen atom, an alkyl group having 1-5 carbon atoms or an alkoxy group having 1-5 carbon atoms; and R5 and R6 independently represent an alkyl group having 1-5 carbon atoms).

摘要： PROBLEM TO BE SOLVED: To obtain a photoreceptor which is sufficient in the improvement of image characteristics and may be easily and stably produced for a long period of time by using pigments treated with active energy rays and/or active gases as n type semiconductor pigments and/or p type semiconductor pigments. SOLUTION: This electrophotographic photoreceptor is constituted by forming photosensitive layers 2, which are successively laminated with a first charge generating transfer layer 6 formed by dispersing the n type semiconductor pigments 3 in a binder resin 5, a second charge generating layer 7 formed by dispersing the p type semiconductor pigments 4 in the binder resin 5 and a second charge layer 8 formed by dispersing a charge generating material and a hole transfer material in the resin in this order, on a conductive substrate 1. The n type semiconductor pigments 3 and/or the p type semiconductor pigments 4 are the pigments treated with the active energy rays and/or the active gases. The n type semiconductor pigments and/or the active gas treatment is preferably executed by irradiating the pigments with the active energy rays in the presence of the active gases and/or under the flow of, for example, the active gases. The samples of the active gases include, for example, gases, such as, oxygen or ozone, and compds. which turn to gases of hydrochloric acid, nitric acid, etc.

摘要： PROBLEM TO BE SOLVED: To obtain an improved liquid developer excellent in dispersion stability, storage stability and image characteristics by using an org. pigment as a coloring agent which is subjected to surface treatment with an oxidizing agent. SOLUTION: This electrostatic charge image developing liquid developer is produced by dispersing toner particles essentially comprising a coloring agent, a binder resin and a charge controlling agent in a highly insulating carrier liquid having a low dielectric const. The coloring agent used consists of an org. pigment subjected to surface treatment with an oxidizing agent. The coloring agent is produced by, for example, irradiating an org. pigment to active energy rays in the presence of an oxidative gas, or by allowing an oxidizing agent to react in a water-base medium. As for the org. pigment, well-known org. pigments, dyes and mixtures of these can be used. As for the org. pigment or dye, conventional well-known pigments or dyes can be used without limitation. Especially a color org. pigment is preferably used.

摘要： PROBLEM TO BE SOLVED: To inhibit power from becoming flocculated and sticking to an internal wall and, enable the efficient and uniform stirring of powder to be achieved by storing the powder in a container with a membrane to be vibrated by a sonic wave at the bottom and giving a mechanical vibration to this container to effect a complex stirring action. SOLUTION: Powder 3 is stored in a container 1 and a membrane 2 is vibrated by giving a sonic wave 7 with the help of a speaker 6 installed at the lower part of the container 1 toward the bottom. Simultaneously, a mechanical vibration is applied to the container 1 using a vibrating motor 9 equipped with a balancer 8. In this case, the powder 3 shows such a fluidized state by the vibration of the sonic wave 7 that the powder 3 seems to be boiling up from bottom to top without being blown up, unless the mechanical vibration is applied. Thus it is adjusted so that the surface of a new powder is constantly moved upward. In addition, the powder 3 on a membrane 2 is caused to show a vortex motion heading for the center of the container from the internal wall by adjusting the balancer 8, when the mechanical vibration is given without the vibration by the sonic wave 7. The efficient stirring action is accomplished as described above.
