摘要:
The object of the present invention is to provide a toner which is excellent in shelf stability for a long term by producing the toner through controlling the dispersion condition of the wax around the toner surface and through improving, not only the off-set resistance of the toner for rendering the fixing properties of the toner advantageous, but also the blocking resistance of the toner, wherein the toner contains a binder resin, a colorant, and a wax, wherein the amount of the wax is 3% by mass to 21% by mass, and the amount of the wax which is present in the portion of the toner particle which is in the range of from the outermost surface to the depth of 0.3 μm in the toner particle is in a specified range, and at least a part of the wax is present as plural individual wax dispersion particles involved in the toner particles.

An image forming process and apparatus, the apparatus including a toner container, a transfer belt below the toner container, a process cartridge below the transfer belt, and an imaging device below the process cartridge. The process cartridge includes a rotating image carrier having an image carrier surface, a brush roller in contact with the image carrier surface, a charging member in contact with the image carrier surface and configured to transfer a charge to the image carrier surface, and a casing including a miler in contact with the image carrier surface and arranged to separate the brush roller from the charging member.

An image forming apparatus performs electrophotographic image forming using a toner and includes an image bearing member configured to bear an electrostatic latent image on a surface thereof, a developing mechanism configured to develop the electrostatic latent image in to a toner image by using a toner, a transfer mechanism configured to transfer the toner image from the image bearing member to an image receiver, a cleaning mechanism including a cleaning blade and configured to remove a residual toner on the image bearing member after toner image is transferred to the image receiver. The toner includes a binder resin and a colorant, forms a toner powder layer, and satisfies an inequality Y≧−0.05X+0.029, in which “X” expresses a porosity of the toner powder layer after uniformly compressed at a constant force and “Y” expresses a torque value obtained by rotatably sticking a conical rotor into the toner powder layer.
摘要:
A toner container densely packed with toner to be replenished into a developing unit included in an image forming apparatus, and a method of producing the same. The toner is packed in the container with a ratio of a packing density to a saturation bulk density greater than 1.0, a mean penetration greater than 5.0 mm inclusive, and a standard deviation of penetration not exceeding one-fifth of the mean penetration. The toner can be smoothly and continuously replenished into the developing unit so as to form a number of images matching the amount thereof.
