Liquid discharge head and image forming apparatus

An image forming apparatus comprising a liquid discharge head that includes:

• a plurality of nozzles that discharge liquid droplets;
• a plurality of individual channels that are in communication with the nozzles;
• a liquid introducing part that is in communication with the individual channels;
• a common liquid chamber that supplies liquid to the individual channels;
• and
• a filter part that is arranged between the common liquid chamber and the liquid introducing part, the titter part having a plurality of filter holes configured to filter the liquid over a range of the individual channels in a nozzle array direction;
• wherein the filter part has at least one reinforcement rib arranged in the nozzle array direction;
• the reinforcement rib is partially arranged over he range of the filter part in a direction perpendicular to the nozzle array direction;
• the reinforcement rib is arranged at a side of the filter part facing toward the common liquid chamber;
• the filter part is divided into filter regions by the reinforcement rib and the filter regions are arranged to be in communication via a communication region of the filter part where the reinforcement rib is not arranged;
• and
• the filter holes in the communication region are arranged at the same position along the nozzle array direction as the reinforcement rib.
