摘要： The present invention provides an image forming process, an image forming device, and a pattern forming process intended to obtain an image by developing a latent image which has been formed by exposing to light a photosensitive material including a photocatalytic layer which includes a photocatalyst and a hydrophobic layer applied on top of said photocatalytic layer, or a photosensitive material including a hydrophobic photosensitive layer which includes a photocatalyst and an organic compound, wherein the photocatalyst, when exposed to light, changes the angle of contact with water in the area on the surface of the photosensitive material which is exposed to light, thereby differentiating from the angle of contact with water in the area which is not exposed to light. The present invention also provides an image forming device and an image forming process which enable on-demand printing and reduce effects on health and environment, as well as a pattern forming process which is simple and reduces the effects on health and the environment.

摘要： A developing apparatus includes an image receptor and a developing unit having a developing roller facing the image receptor. New toner can be added to the developing unit when existing toner in the developing unit is consumed. The added toner and existing toners are formed of cores and external additives. At least one of the cores or the external additives of the added toner is different from that of the existing toner. When the charge amount of the two toners are Q1 and Q2, respectively, the ratio Q1/Q2 is greater than 0.6 and smaller than 1.7, and the absolute values of Q1 and Q2 are 10 μC/g or greater, respectively.

摘要： An electrophotographic image forming apparatus is provided which includes an image receptor on which an electrostatic latent image is formed. A developing unit develops the electrostatic latent image by supplying non-magnetic mono-component toner to the electrostatic latent image and includes a developing roller which faces the image receptor. A trail type regulating blade is installed to form a uniform toner layer on the developing roller. In the electrophotographic image forming apparatus, the rate of the amount of toner particles having a diameter of not more than about half of a median value of a volume-diameter distribution of the toner is not more than about 15% in a number-diameter distribution.
