There is proposed a method of curing an electromagnetic radiation-curing type liquid composition comprising a solvent polymerizable in the presence of an acid, and a photo-acid generating agent which is dissolved in the solvent and capable of generating the acid when irradiated with electromagnetic radiation. This method comprises forming a layer of the electromagnetic radiation-curing type liquid composition on a recording medium, and irradiating electromagnetic radiation including a wavelength which can be absorbed by the photo-acid generating agent onto the composition layer to generate the acid from the photo-acid generating agent, thereby curing the composition layer, which is characterized in that the recording medium is heated on the occasion of forming the layer of the electromagnetic radiation-curing type liquid composition in such a manner that the temperature of the recording medium is increased higher than the temperature of the electromagnetic radiation-curing type liquid composition being delivered onto the recording medium.

There is proposed a washing solution for washing an inkjet printer head which performs printing by feeding an ink comprising at least two kinds of polymerizable compounds each differing in viscosity, a photopolymerization initiator, and pigment. This washing solution is characterized in that it contains not less than 50 parts by weight of a polymerizable compound selected from the polymerizable compounds included in the ink and having a lowest viscosity among the polymerizable compounds, or not less than 50 parts by weight of a polymerizable compound having a viscosity of 30 mPa·sec or less at ordinary temperature.
摘要:
A color image forming apparatus according to the invention includes an intermediate transfer member for transferring a color image onto a paper sheet, a second transfer roller capable of directly transferring, onto a paper sheet, a toner image formed on a photosensitive member to transfer a black-and-white image onto a paper sheet, a first transfer roller for transferring, onto a paper sheet, a color image on the intermediate transfer member. Since the process of transferring a black-and-white image onto a paper sheet is separated from the process of transferring a color image from the intermediate transfer member, a black-and-white image can be transferred onto a paper sheet and fixed thereon immediately after development. Thus, the period required for copying a black-and-white image, in particular, the required first copying period of a black-and-white image can be shortened.

An image forming apparatus comprises a control main body, and reading and recording main bodies detachable to the control main body. The reading main body includes a first memory for storing a read image data memory of original. The recording main body includes a second memory for storing the read image data. The control main body includes a data transmitting circuit for transmitting the image data stored in the first memory to the second memory when the reading and recording main bodies are mounted on the control main body. The recording and reading main body does not only operate alone but also in a state combined with the control main body.
