Abstract
For an image forming apparatus including first and second storage chambers, an inequality expression of 'R2>A×R1' is met. R1 is a sum of a passage resistance value obtained by flowing air through a first air communication portion and a passage resistance value obtained by flowing liquid through a supply portion. R2 is a passage resistance value obtained by flowing air through a second air communication portion. A is a cross-sectional area ratio obtained by dividing a first average cross-sectional area of a first space of the first storage chamber taken along a plurality of horizontal planes by a second average cross-sectional area of a second space of the second storage chamber taken along the plurality of horizontal planes. The first space contains at least a portion adjacent to the supply portion and accumulating the liquid. The second space contains at least a portion accumulating the liquid.
