Abstract
A maintenance and recovery device of a liquid droplet discharge apparatus improves a performance of discharging droplets of a liquid having a high-viscosity. A liquid droplet discharge head () discharges droplets of a recording liquid from a nozzle. A suction cap member () caps a nozzle plane of the liquid droplet discharge head (). An inclined surface () provides a slope toward an evacuation port () on a bottom of the suction cap member (). The inclined surface () forms an inclination angle with respect to a horizontal plane. The inclined surface is formed of a material having a contact angle with respect to the recording liquid. A sum of the inclination angle and the contact angle is equal to or larger than 70 degrees.
