A non-magnetic one-component toner is produced to provide a uniform image density. The non-magnetic one-component toner includes coloration particles that include a binder resin, a pigment, and a charge control agent; and a surface additive including 0.1-4 wt % of one or more selected from the group consisting of silica, titanium oxide, silicon carbide, and alumina, and a resin bead where the surface additive has an average volumetric particle size of 0.01-15 mum where the percentages are based on the total weight of the toner. The non-magnetic one-component toner provides a uniform image density for a long duration and prevents the formation of poor images such as fogging, without performing a separate process such as increasing of the pressure of a cleaning blade or improving the surface smoothness of a latent image drum.
