A toner to develop electrostatic latent images which uses an appropriate combination of a high molecular weight binder resin and a low molecular weight binder resin, an appropriate amount of a releasing agent, and a combination of silica particles and iron oxide particles as external additives, and thus has the following effects: the toner may reduce a generation amount of ultra-fine particles (UFPs) and have enhanced fluidity, charging uniformity, charging stability, transfer efficiency, fixability, durability and a cleaning ability.

Toner to develop electrostatic latent images

An array printhead and an inkjet image forming apparatus having the same are include a first member, a second member, a third member, and a support member. The first through third members and the support member sequentially overlap and couple to each other. The first member supplies ink of different colors into the second member and the second member separately receives the ink of different colors supplied from the first member. The third member includes a plurality of head chips that eject ink supplied from the second member thereon and the support member fixes the first member, the second member, and the third member using a plurality of coupling elements.
