Abstract: A powder replenisher includes a powder replenishment container to be replenished with powder. A pressure adjuster increases and decreases operating pressure applied to a variable capacity portion. A powder measuring instrument measures an amount of the powder that replenishes the powder replenishment container. A controller performs a precise replenishing mode in which, after the controller determines that the powder replenishment container is replenished with the powder in a predetermined amount, while the controller controls the powder measuring instrument to measure the amount of the powder inside the powder replenishment container, the controller controls the pressure adjuster to replenish the powder replenishment container with the powder in a target amount. The controller controls the pressure adjuster to replenish the powder replenishment container with the powder while the controller controls the pressure adjuster based on the operating pressure detected by an operating pressure detector in the precise replenishing mode.

Abstract: A developer set includes a first developer and a second developer. The first developer contains a first toner containing first toner particles and a first carrier containing first carrier particles. The second developer contains a second toner containing second toner particles and a second carrier containing second carrier particles. The first toner particles and the second toner particles each include a toner mother particle and external additive particles attached to the surface of the toner mother particle. The external additive particles include spacer particles. The spacer particles have a number average primary particle diameter of at least 32 nm and no greater than 145 nm. The first carrier particles each include a first carrier mother particle and strontium titanate particles attached to the surface of the first carrier mother particle.
