摘要:
A toner for developing an electrostatic image, which is excellent in low-temperature fixing properties, the prevention of offsetting and uniform chargeability, and which comprises a colorant and a polyester resin modified with an ethyleneimine derivative.
摘要:
Provided are a polyester resin for use in a toner binder which is excellent in terms of offset resistance and low-temperature fixability, which keeps triboelectric charge stability even in an environment of a high temperature and a high humidity, which has excellent durability, and which is used in a toner that gives vivid image characteristics, a process for producing the same, and a toner using the same. The polyester resin for use in the toner binder is formed by linking at least a part of the crosslinked low-molecular polyesters through a dicarboxylic acid used as a linking agent.
摘要:
A toner for developing an electrostatic image comprising at least a colorant and a binder resin,characterized in that the main component of the binder resin is a polyester resin, and the polyester resin is containing a polymer prepared by reacting a polyester oligomer and at least one compound selected form the group consisting of long chain alcohols and long chain carboxylic acids which have 12 or more carbon atoms.
摘要:
A toner for developing an electrostatic image, which is composed of a binder resin and a colorant as main components, said binder resin containing a phenolic hydroxyl group-containing polyester resin as a main component, which toner is energy-saving, suitable for use in a contact heat fixing method using a hot roller, has a high fixing strength at a low temperature and excellent offset preventing properties and is excellent in fixing strength and offset preventing properties in a broad fixing temperature range.
摘要:
A mobile telephone unit which combines operation of a respective portable mobile telephone and a communication unit. The mobile telephone unit includes at least one portable telephone, a communication unit and a buffer unit. The communication unit includes an external connection terminal, a radio transmitter/receiver, a baseband processor, a communication controller and a handset. The buffer unit mounts at least one portable mobile telephone. The buffer unit includes a first buffer unit connector which is connectable to the external connection terminal of the communication unit, a second buffer connector which connects to a connector of a respective portable mobile telephone mounted on the buffer unit, an identifying mechanism for identifying the communication conditions of a respective portable mobile telephone mounted on the buffer unit, and a control signal transmitting mechanism for transmitting the communication conditions identified by the identifying mechanism to the communication controller of the communication unit. The communication controller is responsive to the transmitted communication conditions and adjusts the communication conditions of the communication unit so that a respective portable mobile telephone mounted on the buffer unit can communicate through the communication unit.
