摘要:
Described is a cleaning device for a band-like apparatus. It comprises a hollow rotatable roll supported to turn in the traveling direction of the band-like apparatus. The roll has a plurality of apertures formed in it, and cleaning fluid jet nozzles arranged at the inner side of the plurality of apertures. The cleaning device cleans the band-like apparatus by spraying a cleaning fluid re-at the band-like apparatus from the cleaning fluid jet nozzles. The cleaning device also comprises a plurality of blade plates.

An image forming apparatus comprising: a latent image support for supporting a latent image and a developing device configured to us toner to develop the latent image on said latent image support, the estimated average halftone granularity of the toner imager after developing being 0.25 or less.
摘要:
An electrophotographic image forming apparatus capable of reliably forming an image with density gradation, one which does not have a low-quality appearance. The estimated average halftone granularity of the toner image after developing but before electrostatic transfer was set at 0.25 or less. The average halftone granularity was found by measuring the granularity of a toner image at locations of different average brightness by means of newly proposed formula, and averaging the measured values for which the average brightness is 40 to 80. The estimated average halftone granularity was obtained by estimating the average halftone granularity of the toner image on a photoreceptor by means of a newly proposed method.
摘要:
A developer contains a toner; and a carrier, wherein the toner contains toner particles containing a binder resin; and a colorant, and a titanium oxide as an external additive, wherein an amount of free titanium oxide particles released from the toner determined by a ultrasonic vibration method is from 5 to 22% by weight per total weight of the toner, and wherein the toner has a charge quantity distribution property so that a peak is present in a charge quantity range of from 20 to 40 μC/g in absolute value, wherein the charge quantity distribution of the toner is determined by an increment method in which the developer including the toner is subjected to a blow off treatment to measure a charge quantity of the toner at 23° C. and 55% RH.

A toner for developing an electrostatic latent image, comprising a colorant, a releasing agent and a binder resin, wherein said binder resin comprises a first, non-linear resin, a second, linear resin, and a modified wax comprising a wax moiety and a vinyl polymer moiety having an ester group content of 8 to 30% by weight based on the weight of the vinyl polymer moiety.
摘要:
A toner for developing latent electrostatic images composed of a continuous phase containing a binder resin, and a disperse phase dispersed in the form of finely-divided disperse phases in the continuous phase, containing a resin which is not the same as the binder resin for use in the continuous phase, and finely-divided particles of a releasing agent which are dispersed in the resin, with a coloring agent being dispersed in the continuous phase and/or the disperse phase.
摘要:
A process for fabricating a PTC thermistor device. A pair of opposing electrodes are formed on either major surface of a ceramic plate PTC thermistor element. Metallic plate heat radiation fins are secured to the opposing electrodes by brazing in a non-oxidizing environment. The PTC thermistor element is then heat treated in an oxidizing environment. Optionally, the opposing electrodes may include shield layers for preventing emission of gas from the PTC thermistor element during brazing.
