摘要:
Disclosed is a process for the production of an oxygen-containing organic compound by oxidizing an organic compound with molecular oxygen in a liquid phase in the presence both of a catalytic nitrogen-containing cyclic compound and a catalyst including a solid superacid and, supported thereon, a transition metal compound, in which the nitrogen-containing cyclic compound contains, as a ring constituent, a skeleton represented by following Formula (1), wherein X represents an —OR group, and wherein R represents hydrogen atom or a hydroxyl-protecting group. The process gives the oxygen-containing organic compound in a high yield and enables easy recovery and reuse of the catalyst.

摘要:
An electrophotographic image forming apparatus includes an electrostatic latent image carrying body, an electric charger for uniformly electrifying the carrying body, an optical exposure unit to form an electrostatic latent image on the carrying body, a developer for developing the electrostatic latent image to form a toner image on the carrying body, a transfer unit for transferring the toner image from the carrying body onto a printing sheet, a fixing unit for fixing the toner image to the printing sheet, a cleaner for cleaning to remove residual toner from the carrying body and a toner returning mechanism for returning the residual toner removed by the cleaner to the developer. The developer includes a housing in which a toner chamber is defined, a developing roller rotatably mounted in the housing, an agitator rotatably mounted in the housing so as to be positioned in the toner chamber, a partitioning member provided in the housing for defining a carrier chamber adjacent to the developing roller. The toner returning mechanism includes a toner recirculator for recirculating the residual toner removed from the carrying body to the toner chamber.

Disclosed is an image forming apparatus in which separation unit for electrostatically separating a sheet from a latent image carrier is provided on an openable and closable frame. This image forming apparatus comprises a feeding path for feeding a sheet on which an image is to be formed; an endless latent image carrier; image forming unit for forming a toner image on the latent image carrier; transfer unit for transferring the toner image on the latent image carrier onto the sheet that is conveyed in the feeding path; separation unit for supplying electric charges of an opposite polarity to that of electric charges on a back of the sheet to the back of the sheet in the feeding path at a position downstream of the transfer unit, thereby separating the sheet from the latent image carrier; an openable and closable frame on which at least the separation unit is movably provided and which is to be opened to free the feeding path; a main body frame on which at least the latent image carrier is provided; and a positioning member, provided on the main body frame, for positionin the separation unit by engagement with the separation unit when the frame is closed. With this structure, even when the frame is open or closed, the precision of the position of the separation unit with respect to the latent image carrier can be improved, thus ensuring stable sheet separation.
