An abnormality determining apparatus includes an information storage unit for storing normal index information serving as an index of a normal state of the detection subject, an information obtaining unit for obtaining a plurality of types of information, and an abnormality determining unit for determining the presence of an abnormality in the detection subject on the basis of the normal index information stored in the information storage unit, and the information obtained by the information obtaining unit. The information storage unit stores a plurality of normal index information having different values. The abnormality determining unit selects, at a predetermined timing, normal index information to be used to determine the presence of an abnormality in the detection subject from the plurality of normal index information.

For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

A printing apparatus and a preliminary discharge control method are capable of efficient preliminary discharge control even in a case where a time interval to assure normal printing is equal or nearly equal to the period of one print scanning of an inkjet printhead. In the method, in an inkjet printhead which performs printing by discharging ink from plural print elements while being reciprocate-scanned by a carriage, the number of ink dischargings from each of the plural print elements is counted during print scanning by reciprocate scanning. It is determined whether or not the counted number of ink dischargings from each of the plural print elements is equal to or greater than a predetermined number at predetermined intervals. In accordance with the result of determination, a printable period is updated, and the updated printable period is compared with time necessary for the next print scanning upon completion of one print scanning by reciprocate scanning. Then, in accordance with the result of comparison, preliminary discharge is performed from the inkjet printhead.

The present invention provides a liquid applying apparatus and an ink jet printing apparatus which can reduce evaporation that may occur when a application liquid is left in a liquid holding member for a long time, the liquid holding means forming a space between an elastic member and a roller to hold the application liquid, the apparatuses also being capable of preventing the leakage of the liquid from the liquid holding member regardless of a variation in the posture of the apparatus. In collectitng the application liquid from the liquid holding member to a storage tank, the apparatuses switches a selector valve to allow an air communicating port and a tube to communicate with each other. The apparatuses further drive a pump to collect the application liquid from a liquid applying member and channels to the storage tank. Once the collecting is finished, the air communicating valve is closed.

For a liquid applying mechanism of an ink jet printing apparatus, a liquid to be used for applying it to a medium is prevented from evaporating and leaking from a liquid holding member. An applying roller and the liquid holding member contact with each other to hold the liquid and apply the held liquid to a printing medium by means of the applying roller. In this configuration, the surface of the applying roller has no irregularities. Thereby, the applying roller can contact with the liquid holding member to form an adequate liquid-tight seal therebetween.

In a state deciding apparatus, an information acquiring unit acquires pieces of information of different types related to a state of an image forming apparatus. An index value calculating unit calculates an index value based on the pieces of information acquired. A state change deciding unit decides a change in a subsequent state of the image forming apparatus, based on a temporal change in the index value calculated.

The present invention relates to agents for anti-HIV infection, which contain, as an active ingredient, at least one photosensitizing dye selected from the group consisting of the compounds of the formulae (I) and (II): wherein R1, R2 and R3 are the same or different and each represents alkyl group having 1 to 4 carbon atoms, R4, R5 and R6 are the same or different and each represents alkyl group having 5 to 10 carbon atoms, and X− represents a physiologically acceptable monovalent anion. The present invention also relates to a method for treating or preventing HIV infection diseases, which includes administering the photosensitizing dye. A daily dose of the photosensitizing dye is usually 2 to 100 &mgr;g, and preferably 5 to 40 &mgr;g, per kg body weight. Administration of the photosensitizing dye to HIV infected subjects leads to improvement or cure of the symptoms of AIDS related complex and increase in CD4-positive lymphocytes, which is effective for the treatment of HIV infection diseases.

An image forming apparatus includes a latent image bearing member, a charging unit, a charging power source, a latent image writing unit, a development unit, a transfer unit, a toner detector, and a controller. The controller causes a background fog pattern to be formed on a surface of the latent image bearing member. In addition to the background fog pattern, the controller causes a latent image to be developed to form a toner image used for position identification on the surface of the latent image bearing member. The controller identifies a time when the toner image used for position identification has entered a detection range of the toner detector based on a change in outputs of the toner detector to determine a time when each of sections of the background fog pattern enters the detection range based on the identified time.
摘要:
An inkjet printing apparatus is provided which minimizes the amount of inks consumed for preventing the sedimentation of ejected inks on the platen ink absorber and which can effectively prevent the sedimentation of inks. To this end, a comparison is made between the ejected volume of easily sedimenting inks and the ejected volume of sedimentation restraining inks in terms of ink components. If the ejected volume of the sedimentation restraining inks is found not enough, a required amount of sedimentation restraining ink is additionally ejected.
