    Abstract: A control portion sets, as a control period, a period after arrival, at a position opposite a recording head, of a first recording medium until passage, at the position opposite the recording head, of a last recording medium. The control portion sets nozzles that do not face the recording medium during the control period as first nozzles, and nozzles that face the recording medium during the control period as second nozzles, to make the total amount of ink ejected by each of the first nozzles in flashing processing during the control period smaller than the total amount of ink ejected by each of the second nozzles.

    Abstract: A toner contains toner particles. The toner particles each include a toner mother particle and an external additive attached to the surface of the toner mother particle. The external additive contains specific external additive particles. The specific external additive particles each include an aluminum oxide particle and a coat layer covering the surface of the aluminum oxide particle. The coat layers contain antimony tin oxide particles. The specific external additive particles have a powder specific resistance of no greater than 100 Ω·cm. The specific external additive particles have a volume median diameter of 100 nm to 550 nm. The specific external additive particles have surfaces with an arithmetic mean roughness Ra of 8 nm to 45 nm. The specific external additive particles have a content of 0.3 parts by mass to 4.0 parts by mass relative to 100 parts by mass of the toner mother particles.

    Abstract: An image forming apparatus includes a print device, a first backend communication portion, a second backend communication portion, and an inquiry management portion. The inquiry management portion transmits, when determining that transmission of a permission response is possible, the permission response to a digital frontend via the first backend communication portion. The second backend communication portion receives print data from the digital frontend. The print device executes print processing that is based on the print data when the print data is received from the digital frontend by the second backend communication portion.
