Abstract: An image forming apparatus includes a first liquid applier, a second liquid applier, a conveyor, and a heater. The first liquid applier applies liquid to a first side of a recording medium. The second liquid applier applies the liquid to a second side of the recording medium bearing the liquid applied to the first side by the first liquid applier. The conveyor conveys, in a conveyance direction, the recording medium bearing the liquid applied to the second side by the second liquid applier. The heater heats the recording medium conveyed by the conveyor. The conveyor conveys the recording medium in contact with the first side of the recording medium. The heater heats the recording medium at different temperatures between an upstream location and a downstream location in the conveyance direction of the recording medium.

Abstract: A liquid discharge apparatus includes a liquid discharge head including a supply port, a recovery port, and nozzles to discharge a liquid from the nozzles, a circulation channel connected to the supply port and the recovery port of the liquid discharge head to circulate the liquid through the liquid discharge head, and a cap to cap a nozzle surface of the liquid discharge head in which the nozzles are formed and to suck the liquid from the nozzles in a maintenance operation. The circulation channel includes an individual supply channel communicating with the supply port of the liquid discharge head, an individual recovery channel communicating with the recovery port of the liquid discharge head to circulate the liquid through the liquid discharge head, a supply-side fluid resistance variable section disposed in the individual supply channel to vary fluid a resistance of the individual supply channel.
