摘要： PURPOSE:To obtain a toner good in reversal and normal developability, superior in high speed fixability, good in offset resistance and storage stability by using a binder resin composed of polyester, polyamide, and vinyl type resins. CONSTITUTION:A binder resin used for the present toner contains a polyester resin produced from dicarboxylic acid contg. polyol or polycarboxylic acid, and diol, such as etherified bisphenols; a polyamide resin produced by reaction of a dimer acid with di- or poly-amine, and a vinyl type resin, such as copolymers of styrene and alpha-methylene aliphatic carboxylic ester, both for the purpose of raising positive triboelectrifiability; in a composition of 25-75% polyester, 5-50% polyamide, 25-75% vinyl type resin on the weight basis; and further, an offset inhibitor. As a result, the obtained toner is superior in positive triboelectrifiability with said polyamide, improved in insulating property, humidity and heat resistances, and superior in fixability and offset resistance with the vinyl type resin.

摘要： PURPOSE:To obtain high sensitivity and superior durability by dividing the electrostatic charge transfer layer of a composite type photosensitive body into the upper and lower layers and interposing an interlayer capable of transferring charge and made of an alcohol-soluble resin. CONSTITUTION:The charge transfer layer of a composite type photosensitive body formed on a conductive substrate 1 is divided into the upper and lower layers 4, 3 and an interlayer 5 capable of transferring charge between both and made of an alcohol-soluble resin. The interlayer 5 is made of an acrylate resin represented by the formula in which R1 is H or methyl, and R2 is a univalent org. group. The charge transfer layer thus divided into the layers 3, 4 can be formed overall thicker and increased in chargeable amt., enhanced in charging speed. Surface hardness and corona resistance can be enhanced by lowering the concn. of the charge transfer material in the charge transfer layer 4 located near the surface of the photosensitive body and doing the like, and a photosensitive body high in strength and abrasion resistance can be obtained. As a result, the obtained composite type electrophotographic sensitive body has high sensitivity and superior durability.
