摘要： An image forming apparatus including: a carriage movable in a main scanning direction and including a recording head having a nozzle surface in which nozzles to eject liquid droplets in a horizontal direction are formed, the nozzle surface being disposed in a vertical direction; a guide shaft to guide the carriage in the main scanning direction; and a bearing provided to the carriage and having two sloped sides slidably contacting an outer circumferential surface of the guide shaft. In a plane perpendicular to an axis of the guide shaft, the two sloped sides are disposed such that a line passing through both the axis of the guide shaft and an intersection of two tangent lines from contact portions in which the two sloped sides contact the outer circumferential surface of the guide shaft diagonally intersects a line extending along a plane of the nozzle surface.

摘要： An image recording apparatus includes a recording head including a plurality of nozzles from which ink is ejected, a memory, and one or more hardware processors coupled to the recording head and the memory. The one or more hardware processors are configured to: determine, for each of the plurality of nozzles, whether a position of the corresponding nozzle is a position to eject ink; determine whether a successive ejection operation is necessary for a nozzle out of the plurality of nozzles, whose position is determined as the position to eject ink; and cause ink to be successively ejected at the position to eject ink at a predetermined successive ejection frequency from the nozzle that is determined to have the necessity of the successive ejection operation.
