    摘要： Provided is a toner that allows a transferred image to be stably output regardless of smoothness of a transfer material even under high-temperature and high-humidity environment or under low-temperature and low-humidity environment, that is excellent in cleanability for a transfer member even at the time of high-speed printing, and that causes less member contamination. The toner is a toner including toner particles each containing a binder resin and a wax, and silica fine particles on surfaces of the toner particles, wherein the silica fine particles have a number-average particle diameter of primary particles of 60nm or more and 300nm or less, a coverage rate of the surfaces of the toner particles with the silica fine particles is 15% or more and 95% or less, and the toner has a uniaxial collapse stress at a maximum consolidation stress of 10.0 kPa, of 2.5 kPa or more and 3.5 kPa or less.

    摘要： Provided is a developer replenishing cartridge excellent in accuracy with which an image forming apparatus is replenished with a developer irrespective of a use environment even when the developer is in a consolidated state. The developer replenishing cartridge includes: a developer replenishing container and a developer, being removably mountable to a developer replenishing apparatus; in which: the developer replenishing container includes a pump portion that operates so that a state where the internal pressure of a developer containing portion is lower than the atmospheric pressure and a state where the pressure is higher than the atmospheric pressure alternately repeatedly switch with each other; and the developer contains toner having a uniaxial collapse stress at a maximum consolidation stress of 10.0 kPa, of 2.5 kPa or more and 3.5 kPa or less.

    摘要翻译： 本发明提供一种显影剂补充盒，即使显影剂处于合并状态，也能够向显影剂补充显影剂，而不管使用环境如何，其精度优异。 显影剂补充盒包括：显影剂补充容器和显影剂，可拆卸地安装到显影剂补充装置; 其中：显影剂补充容器包括泵部分，该泵部分操作使得显影剂容纳部分的内部压力低于大气压力的状态和高于大气压力的压力状态交替地彼此重复切换 ; 并且显影剂含有在10.0kPa的最大固结应力下具有2.5kPa或更大且3.5kPa或更小的单轴倒塌应力的调色剂。
