An image forming apparatus includes a plurality of toner reservoir for storing different toner, a developing unit composed of a plurality of developing devices, and a plurality of toner conveyors for conveying toner from the toner reservoir to the developing unit. Through-holes are formed in the developing unit, and an upper portion of each through-hole is connected with each toner conveyor in such a manner that an upper opening of each through-hole is opposed to an ejection port of each toner conveyor, so that toner drops from the toner conveyor into through-hole and is guided to each developing device.

An image forming apparatus having a carriage which can be pulled out from an installed position thereof. The carriage supports a cartridge including an image forming body, at a pull-out position, and fixes the cartridge to a position at which an image can be formed, at the installed position of the carriage. When the carriage is located at the installed position, the carriage forms at least a part of the upper surface of a main body of the apparatus.

A nitrocarburized microalloyed steel member consists of a microalloyed steel that includes a nitrocarburized layer on a surface, a cross-sectional structure of which steel except for the nitrocarburized layer includes a ferrite and pearlite structure. The microalloyed steel mainly consists of Fe and has a composition: C having a content of 0.30 mass % or more and 0.50 mass % or less; Si having a content of 0.05 mass % or more and 0.30 mass % or less; Mn having a content of 0.50 mass % or more and 1.00 mass % or less; S having a content of 0.03 mass % or more and 0.20 mass % or less; Cu having a content of 0.05 mass % or more and 0.60 mass % or less; Ni having a content of 0.02 mass % or more and 1.00 mass % or less; and Cr having a content of 0.05 mass % or more and 0.30 mass % or less. If the contents of the Cu, the Ni, and the Cr are represented by WCu, WNi, and WCr mass %, respectively, and composition parameters F1 and F2 are 185WCr+50WCu and 8+4WNi+1.5WCu−44WCr, respectively, then the composition parameters F1 and F2 satisfy F1>20 and F2>0.

A throwaway drill capable of machining a workpiece stably in a balanced manner even under high-efficiency, high-load conditions and capable of disposing of chips efficiently and smoothly. The drill carries an outer insert and an inner insert. As shown, each insert has a plurality of cutting edges each having a curved crest, a first slope, and a second slope which is at least partially a curved line. The inner and outer inserts are arranged so that the cutting area to be cut by the outer insert alone is partially cut by a cutting edge portion of the inner insert near its corner, and the cutting area which to be cut by the inner insert alone is partially cut by the crest of one cutting edge of the outer insert.

A basic joint member and a plurality of application joint members are formed so that a side plate portion or end plate portion is fitted to the end face of a construction member constituting a post, a beam or the like and a coupling plate portion extending from the side plate portion or end plate portion orthogonally to the side plate portion or end plate portion is fitted in a groove formed in the end face of the construction member or is gripped between construction members including two parallel members, and the connecting plate portion is clamped by a clamping member. The basic member containing a longitudinal construction member is combined with and connected to at least one application joint member for a lateral construction member, a lateral construction member orthogonal to the first-mentioned lateral construction member and an oblique construction member to construct a joint apparatus for construction members. Furthermore, a construction method using this joint apparatus and a building constructed according to this construction method are provided.
