摘要： A charging device (10) includes electrospray means for inducing electrospraying through application of a voltage to an incoming liquid (11), in order to produce charged liquid droplets (13). The device (10) charges a photoreceptor drum (1) by means of the liquid droplets (13). Hence, the invention provides a charging device capable of reducing ozone production while preventing the charging device and the electrostatic latent image carrier from degrading or wearing out from friction between the device and the carrier and provides also an image forming device incorporating the charging device.

摘要： A toner composed of small particles excellent in a cleaning property, a transferring property, and charge uniformity is provided as well as a method of manufacturing the toner, and two-component developer, developing device, and image forming apparatus using the toner. The toner contains binder resin and colorant, and includes a particle which has an outline having one or more and three or less bending points in its projection image on a plane. The toner thus contains a non-spherical particle and therefore is caught easily by a cleaning blade as well as coming into point-contact with a to-be-transferred member, therefore being capable of having both of cleaning property and transferring property.

摘要： An electron emitting element is of a structure in which a semiconductor layer is formed between an upper electrode and a lower electrode, wherein an organic compound adsorption layer is formed on a semiconductor surface of the semiconductor layer by causing the organic compound to be adsorbed on the semiconductor surface. Herein, the semiconductor layer can be made of silicon or polysilicon and partly or as a whole porous. The absorbed organic compound can be a non-cyclic hydrocarbon, a compound obtained by coupling at least an aldehyde group to a non-cyclic hydrocarbon, or a non-cyclic hydrocarbon having an unsaturated bond. As a result, there can be provided an electron emitting element capable of stably operating in the atmosphere or in a low vacuum even when being operated in the atmosphere or in the low vacuum and an imaging device using the electron emitting element.

摘要： Provided are an electron emitter continuously emitting electrons stably even in the atmosphere, a charger using the electron emitter, and a charging method using the charger. The electron emitter includes a electron emitting element consisting of a first electrode, a second electrode, and a semiconductor layer formed therebetween, and a power supply for alternately applying a positive voltage enabling electron emission and a negative voltage having a polarity opposite to the positive voltage. At least a part of the surface on the first electrode side of the semiconductor layer is formed of a porous semiconductor layer. Electrons captured in the porous semiconductor layer in the course of electron emission with application of a positive voltage disturb electron emission from the electron emitting element. Such electrons, however, are removed by application of a negative voltage.
