摘要:
A method and an apparatus for modifying a surface layer formed on the surface of a base material in order to modify the characteristics of the surface layer such as to control the chemical composition of the surface layer and to develop a novel utilization of ultra-pure water.The method includes the step of contacting a surface layer on a base material with ultra-pure water in an oxygen-free atmosphere. The amount of dissolved oxygen in the water is preferably 1 ppm or below, and the ultra-pure water is preferably boiled.The apparatus includes a chamber having inert gas introduction means for introducing an inert gas thereinto, and inert gas discharge means for discharging the inert gas therefrom, a container disposed inside the chamber for holding ultra-pure water, and heating means disposed in the chamber for heating ultra-pure water held in the ultra-pure water container.
摘要:
An image forming apparatus includes an image bearer rotating in a first direction while bearing a toner image thereon in a normal image forming operation; a toner image forming device to form the toner image on the image bearer; a transferring device to transfer the toner image to a recording medium eventually; a cleaning blade to block toner remaining on image bearer without being transferred; and a controller. The controller controls the image bearer to perform an inverse rotation operation in which the image bearer rotates in a second direction opposite to the first direction after controlling the toner image forming device to perform a special image forming operation such that the amount of toner input to the cleaning blade in the special image forming operation is greater than the amount of toner input to the cleaning blade in the normal image forming operation, and then stopping the image bearer.

The present invention provides a liquid application device and an ink jet recording apparatus each capable of reducing deterioration in application quality due to an increase in the number of times of use of a roller, thereby improving durability. The present invention includes an application roller which applies liquid to an application medium, and a liquid retention member which retains the liquid in a liquid retention space formed by making the application roller be in contact with the retention member. With this structure, a pool of the liquid is formed, with rotation of the application roller, in an area upstream of a contact area, in a rotational direction, between the application member and the retention member at a side where a surface of the application member enters the contact area therebetween.

The development device includes a toner carrier, a toner supplier, and a surface electrical potential controller. When the toner supplier supplies toner particles to the toner carrier, the toner carrier carries toner particles to adhere to a latent image formed on the latent image carrier and has a time constant τ1 of a surface electrical potential change of the toner carrier. The surface electrical potential controller has a time constant τ2 of a surface electrical potential change of the toner carrier smaller than the time constant τ1. The toner carrier includes a plurality of electrodes aligned in parallel and electrically insulated from each other on the surface thereof, and a voltage supplier for supplying each of the plurality of electrodes with a voltage to periodically switch electrical fields therebetween, so that the toner particles form a cloud on the surface of the toner carrier while hopping.
摘要:
Provided are an inkjet printing apparatus and a method of controlling an inkjet printing apparatus whereby the performing of a suction discharge operation, for air bubbles that have penetrated inside an ink supply line, can be suppressed to a minimum necessary number of times, and whereby the ink discharge volume that accompanies air bubble suction discharge operations can be kept low. The volume of an air bubble that penetrates into an ink supply line is estimated on the basis of an elapsed time since the last air bubble suction discharge operation, and in addition, the volume of an air bubble that penetrates into the ink supply line during main tank installation is predicted. The suction discharge operation (choke suction operation) for suctioning out and discharging air bubbles is conducted when the sum of these estimated volumes becomes equal to or greater than a predetermined value.

The inkjet printer in the present invention can discharge a bubble in an ink flow path while suppressing ink consumption. Ink in an ink tank is supplied to a printing head through a flow path and filter 48. Bubbles in the flow path and printing head 22 are discharged by applying a negative pressure to an ejection port of the printing head. At this time, after a first negative pressure has been applied to the ejection port with an on/off valve provided between the ink tank and the filter being closed, the on/off valve is opened to discharge the ink from the ejection port. Further, after that, a second negative pressure that prevents a bubble from passing through the filter is applied to the ejection port to discharge a bubble present more closely on the printing head side than the filter from the ejection port together with the ink.
