Liquid jet recording head and liquid jet recording apparatus

Abstract

A liquid discharge head comprises recording liquid flow paths communicated with plural discharge ports for discharging liquid droplets; a flow path formation member on the upstream of the recording liquid flow path on which a recording liquid supply passage for supplying recording liquid to the recording liquid flow path is provided; a recording liquid storing member on the upstream of the recording liquid supply passage on which a common liquid chamber for containing recording liquid to be supplied to the recording liquid supply passage is provided; a plug member for supplying recording liquid from the outside into the common liquid chamber; and a porous member held at the end portion of the flow path formation member to remove dust particles and others in recording liquid supplied from the common liquid chamber to the recording liquid supply passage. In this liquid jet recording head, the porous member is arranged above a bottom face of the common liquid chamber. With the structure thus arranged, it is made difficult for colorant, dust particles, and the like accumulated on the bottom face of the common liquid chamber to be accumulated again on the surface of the porous member.
