摘要： A liquid discharge head includes a nozzle to discharge a liquid, a pressure generation chamber facing the nozzle, a common liquid chamber to supply the liquid to the pressure generation chamber, a fluid restrictor communicating with the pressure generation chamber, and a guide channel communicating with the fluid restrictor and the common liquid chamber. The guide channel includes a first adjacent portion communicating with the fluid restrictor. The pressure generation chamber has a first resonance period, and the guide channel has a second resonance period different from the first resonance period.

摘要： A liquid discharge head includes a nozzle to discharge a liquid, an individual chamber communicating with the nozzle, a supply channel communicating with the individual chamber to supply the liquid to the individual chamber, and a discharge channel communicating with the individual chamber to discharge the liquid in the individual chamber. A fluid resistance of the supply channel is greater than a fluid resistance of the discharge channel.

摘要： A liquid discharge head includes a channel plate. The channel plate includes a fluid restrictor, a channel, a first plate member, and a second plate member. The channel is disposed on at least one of an upstream side and a downstream side of the fluid restrictor in a direction of flow of liquid. The channel has a greater width than a width of the fluid restrictor in a direction perpendicular to the direction of flow of liquid in an in-plane direction. The first plate member has a through hole including at least one broad portion and a narrow portion. The narrow portion is the fluid restrictor. The second plate member includes at least one through hole constituting part of the channel with the broad portion. The through hole is disposed opposite an end of the narrow portion at which the narrow portion is connected to the broad portion.

摘要： An electrophotographic printer capable of easily attaching and detaching a retaining means to retain the inside of a photoconductive drum to and from the photoconductive drum. A flange located on the extraction side of a photoconductive drum is provided with: a retaining means to support the photoconductive drum from the side of the inner circumferential face of the photoconductive drum. And an advance and retreat mechanism to advance and retreat the retaining means to and from the inner face of the photoconductive drum. The retaining means can be easily dismantled from the photoconductive drum by operating the advance and retreat mechanism, and thereafter extracting the flange from the photoconductive drum.
