Abstract
There is provided a recording apparatus capable of outputting an image which is not provided with nonuniformity of printing, stable and provided with high quality by realizing a recording head for maintaining a shape of a meniscus of ink always in a proper state without carrying out highly accurate back pressure control. Hence, a shape of front ends of base plates forming a slit-like opening portion is constituted by a shape of a wedge directing a sharpened front portion thereof to a recorded medium. Further, an inclined face portion in the shape of the wedge is subjected to a water repellant or an oil repellant processing. Or, there is constructed a constitution of providing an ink discharge mechanism for discharging extra ink at an end face portion at outside of a printing area of the base plate constituting the slit-like opening portion.
