摘要： A positively chargeable single-component developer for visualizing electrostatic latent images comprises a binding resin having an acid value of 1.5 to 10 (KOH mg/g), a colorant, and an additive such as polyfluoroethylene fine powder having an electron attractive group. The additive is added in an amount of 0.05 part by weight to 2 parts by weight with respect to 100 parts by weight of the positively chargeable single-component developer. The acid value of the binding resin may be adjusted by mixing two or more resins having different acid values. The developer prevents a surface of a photosensitive member from decrease in electric potential which would be otherwise caused by electrons released when toner particles and the photosensitive member are frictionally charged. Accordingly, the developer makes it possible to provide good image quality with less fog and with a dense density.
摘要翻译：用于可视化静电潜像的带正电荷的单组分显影剂包括酸值为1.5至10（KOH mg / g）的粘合树脂，着色剂和具有吸电子基团的聚氟乙烯细粉末等添加剂。相对于100重量份的带正电荷的单组分显影剂，添加剂的添加量为0.05重量份至2重量份。可以通过混合两种以上具有不同酸值的树脂来调节粘合树脂的酸值。显影剂防止感光构件的表面降低电位，否则当调色剂颗粒和感光构件被摩擦带电时，电子被释放。因此，显影剂使得可以以更少的雾度和更密集的密度提供良好的图像质量。

摘要： An electrostatic latent image developer is produced by adding 1 part by weight or more of an agent improving transfer efficiency, the agent having an average particle size of 0.1 to 3 .mu.m, together with 0.3 to 5 parts by weight of a hydrophobic silica fine powder of a BET specific surface area of 50 to 300 m.sub.2 /g to 100 parts by weight of a toner. The electrostatic latent image developer of the invention improves the transfer efficiency from a photosensitive material onto a recording medium while the flowability of the toner can be retained, whereby any cleaning mechanism in a developer system can be omitted.

摘要： An image-forming apparatus forms an image by applying a control electric field having a polarity corresponding to recording information, to a recording medium having microcapsules including chargeable particles dispersed in a dispersion medium. The image-forming apparatus includes an alternating electric field-applying unit for applying an alternating electric field to the microcapsules. The alternating electric field is applied to the microcapsules of the recording medium before the image formed on the recording medium is rewritten. Accordingly, the chargeable particles are separated from the wall surfaces of the microcapsules and from the other chargeable particles, making it possible for the chargeable particles to perform free electrophoresis. The recording medium is initialized to improve the response performance with respect to the control electric field for forming a new image. The recording density is increased, and the blur is reduced.
