Abstract: An example photodetector for detecting fluorescent toner includes a light emitting unit to emit light to a toner image, and a light receiving unit. The light receiving unit is to detect visible light reflected by the toner image, detect that the toner image includes the fluorescent toner based on the detection of the visible light, the visible light generated by the fluorescent toner and having a predetermined wavelength band different from a wavelength band of the emitted light, and output a signal corresponding to the detection of the fluorescent toner.

Abstract: An image forming apparatus includes a developing unit, a transferring unit, and a fixing unit. The developing unit performs an attachment process in which the developing unit attaches a luminescent toner to a latent image that is formed on a basis of image data. The transferring unit performs a transfer process in which the transferring unit transfers, onto a medium, the luminescent toner attached to the latent image. The fixing unit performs a fixing process in which the fixing unit fixes, to the medium, the luminescent toner transferred onto the medium. The attachment process performed by the developing unit and the transfer process performed by the transferring unit are each performed plural times for the medium, on the basis of the image data.

Abstract: An apparatus and method of manufacturing a white dry ink pulverized toner including a resin and 15%-45% TiO2 pigment having a mean size of 100-350 nm melt mixed with the resin in a twin screw extruder resulting in an extruded mix. The extruded mix is pulverized in a fluid bed jet mill. Fines of the pulverized extruded mix less than 5 microns may be removed from the pulverized extruded mix by classification leaving pulverized particles having a mean size of 6-12 microns. The pulverized particles are blended in a mixer with surface additives including silica and ZnSt, and the white dry ink pulverized toner has a developer charge between 5 and 50 μC/gram and a Lightness (L*) of at least 75 at a toner mass per unit area (TMA) of at most 1.2 mg/cm2.
