摘要： Provided are a method of manufacturing a ceramic article including a porous portion in which improvement in mechanical strength of a modeled article is achieved while high modeling accuracy is obtained, and a ceramic article. The method of manufacturing a ceramic article includes the steps of: (i) irradiating powder of a metal oxide containing aluminum oxide as a main component with an energy beam based on modeling data to melt and solidify or sinter the powder, to thereby form a modeled article including a porous portion; (ii) causing the modeled article formed in the step (i) to absorb a liquid containing a zirconium component; and (iii) heating the modeled article that has absorbed the liquid containing the zirconium component, wherein, in the absorbing step, the liquid is absorbed so that a ratio of the zirconium component in a metal component contained in the porous portion becomes 0.3 to 2.0 mol %.

摘要： An image forming apparatus includes a first supporting member supporting a long sheet, a feeding unit for feeding the long sheet supported by the first supporting member with respect to a feeding direction and a second supporting member, rotatable about a rotational shaft, for supporting the long sheet with the first supporting member. In a state in which the sheet is bent so that a first portion of the long sheet is supported by the first supporting member and a second portion which is a more rear side than the first portion is positioned above the first portion, the second supporting member is movable between a first position where the second supporting member supports the second portion of the sheet and a second position where the center of gravity of the second supporting member is positioned downstream of a rotational center with respect to the feeding direction and the second supporting member maintains an attitude thereof by its own weight.
