摘要:
The present invention provides a toner comprising a binder resin, a colorant and an infrared absorbing agent, wherein tan δ (loss elastic modulus G″/storage elastic modulus G′) of the toner at 120° C. is in the range of 3 to 6, and an image-forming method using the toner in which toner images on a recording medium are light irradiated by a flash lamp having a light-emitting energy of 1.0 to 5.0 J/cm2 so that the toner images are fixed on the recording medium.

摘要:
The present invention relates to a mono-component developing device, which develops an electrostatic latent image formed on an electrostatic latent image-supporting member with a toner having a weight-average particle size of from 4 to 10 &mgr;m, a compression rate of not more than 32% and an angle of repose of not more than 38°, and a toner used for the mono-component developing device. Even in the case when a comparatively great stress is imposed on the toner particles, the toner of the present invention maintains superior fluidity and makes it possible to provide a high-quality image.

A forceps includes a pair of grip pieces which are pivotally supported about a first fulcrum to be mutually openable and closable. A pair of tip-end forceps pieces are pivotally supported about a second fulcrum to be mutually openable and closable. The second fulcrum is separated from the first fulcrum. An operation transferring member transfers opening and closing operation of the grip pieces about the first fulcrum to opening and closing operations of the tip-end forceps pieces about the second fulcrum.

The present invention relates to a recycle developing process which comprises developing an electrostatic image formed on a photosensitive material with a starting developer filled in a developing vessel, transferring the toner image to a predetermined paper, recovering the toner remaining on the photosensitive material by a cleaning means, and repeating the developing procedure while replenishing a virgin toner and the toner recovered by the cleaning means into the developing vessel; wherein the virgin toner to be replenished into the developing vessel is that which is fulfilled in a container wherein a rotating roller is provided in an opening portion at a lower portion has a flowability, shown as a fallen amount of the toner at a time of falling via the rotating roller for a certain fixed time, of 50 to 70% based on the toner in the starting developer.According to this process, an abrupt decrease in the properties of the developer due to the mixing of the recovered toner can be relaxed. As a result, a stable image free from fogging or toner scattering can be formed by the recycle developing process.
