Abstract
A pipeline arranged so that any bubbles mixed in a liquid developer can be prevented from being delivered to a developing section. A main pipe through which the pumped developer flows is communicated at its lower end with a branched pipe. A branched pipe which is communicated with the developing section is connected to the branched pipe through a portion which is sloped downward in a direction in which the developer flows. Accordingly, air bubbles in the developer having reached the branched pipe are allowed to rise in the sloped portion to return to the branched pipe. There is therefore no fear of air bubbles being supplied to the developing section.
