摘要:
A toner comprising a toner binder and a colorant, composed of resin particles produced by causing an extension reaction and/or crosslinking reaction of a dispersion formed of a reactive group-containing prepolymer (&agr;) contained in an aqueous medium with an extension agent and/or a crosslinking agent (&bgr;). The toner has a Wadell practical sphericity of 0.90 to 1.00 and is superior in fluidity, transferability, the storage stability under heat, low temperature fixing ability and hot offset resistance.
摘要:
Provided by the present invention are (1) a dry toner excellent in powder flowability and transferability when formed as a small-particle-size toner; (2) a dry toner excellent in any one of heat storage stability, low-temperature fixing property and anti-hot offset property; (3) a dry toner excellent in gloss exhibition when an image is formed by a full color copying machine; and (4) a dry toner which does not need application of an oil to a heat roll. Described specifically, provided by the present invention is a dry toner comprising a toner binder and a colorant, wherein the toner has a Wadell's practical sphericity ranging from 0.90 to 1.00, the toner binder contains a high-molecular-weight condensation resin (A) and a low-molecular-weight condensation resin (B), a ratio (MnA/MnB) of the number average molecular weight (MnA) of the resin (A) to the number average molecular weight (MnB) of the resin (B) is at least 1.6, and a ratio (MwA/MwB) of the weight average molecular weight (MwA) of the resin (A) to the weight average molecular weight (MwB) of the resin (B) is at least 2.

A1 A communication system comprises obtaining a corresponding dynamic address by sending an identifier to a mapping notification system which stores a pair of an identifier and a dynamic address; and determining whether or not a dynamic address stored in the mapping notification system is correct by accessing other communication node to which the dynamic address obtained by the obtaining means is assigned. The system also compares the identifier sent to the mapping notification system and a reply for the access to the communication node. If the system determines that the address is not correct, the obtaining process and determination process are executed again, an execution of a process to be executed after the determination process is stopped, or a control process for preventing from sending back a reply of the address from the mapping notification system is executed.
摘要:
A rotary switch includes a rotor that is insert molded so upper and lower contact pieces have a predetermined number of contact regions with a predetermined angular width in each of a plurality of annular zones defined by a plurality of concentric circles and are stacked in a disk part. The contact pieces are exposed in two surfaces of the disk part, an upper contactor holder and a lower contactor holder are placed to cover a lower half and an upper half of the disk part of the rotor. A plurality of elastic contacts are brought into elastic contact with lower and upper side surfaces of the disk part in a plurality of annular zones, and a rotating operation shaft is inserted through the rotor, the lower contactor holder, and the upper contactor holder, and can rotate the rotor.
