The present invention relates to organic polymer porous materials, and in particular, to an organic polymer porous material that functions as a reusable insoluble solid catalyst and a method for producing the same. The organic polymer porous material of the present invention is characteristic in that the amount of immobilized bases is high and the specific surface area is large. The object has been achieved by an organic polymer porous material including a polymer (PA) obtained by polymerizing a polymerizable composition (A) containing a compound (a) obtained by reacting a dendrimer (a1) having at least an amino group as a reactive functional group or a polyethyleneimine (a2) having at least an amino group as a reactive functional group with a compound (a3) having a vinyl group and a group that can react with the reactive functional group.

An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The output value Vt of the magnetic permeability sensor and the target output value Vtref are compared, and the toner density is controlled by controlling a powder pump on the basis of the comparative result thereof so that the output value Vt approximates the target output value Vtref. In addition, the target output value Vtref is corrected on the basis of the detected result of the image coverage ratio so as to maintain a predetermined development potential of the development apparatus. By virtue of this, even when image forming that involves a significant change in the toner replacement amount in the development apparatus is performed, for example, even when an image of high image coverage ratio is output, the toner density is adjusted to maintain the development capability at a constant, and a predetermined image density is ensured. Moreover, because the image coverage ratio can be detected without consuming toner, toner does not need to be consumed when the target output value Vtref is corrected.
摘要:
An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The toner density of the developer is controlled so that an output value Vt of a magnetic permeability sensor approaches a target output value Vtref. In addition, the target output value Vtref is corrected in accordance with image coverage history information of output images transferred to a transfer paper and image coverage ratio history information of output images determined from the image coverage thereof and the size of the transfer paper. This history information comprises, for example, a cumulative average value of the image coverage or the image coverage ratio per transfer paper. It may also comprise a moving average value of the image coverage or the image coverage ratio per transfer material.

An image forming apparatus includes an image carrier, a developing unit, a concentration sensor, a toner supplying unit, a developer supplying unit, an ejector, and a condition detector. The image carrier forms a latent image thereon. The developing unit develops the latent image formed on the image carrier with a two-component image developer including toner particles and carrier particles. The concentration sensor detects a toner ratio in the developing unit. The toner supplying unit supplies fresh toner particles to the developing unit. The developer supplying unit supplies fresh image developer to the developing unit. The ejector ejects the image developer to an outside of the developing unit. The condition detector detects a condition of the image developer used for an image forming operation to determine a supply amount of the image developer to supply to the developing unit. The condition includes a degradation level of the image developer.

A black developer is conveyed in a first conveyance chamber in a rotation axis direction while agitating with rotation of a first screw member. A black-toner-concentration detecting sensor detects a toner concentration of the black developer by having contact with the black developer conveyed inside the first conveyance chamber. An average of peak amounts of a pressing force on the black developer, which is conveyed inside the first conveyance chamber by the first screw member, with respect to the black toner-concentration detecting sensor is set within a range of 9.8 15 [N/m2] to 9.8 100 [N/m2].

An ion generator that can generate a controlled trace amount of ozone together with negative or positive ions. The ion generator includes an insulation substrate, a ground electrode and a high-voltage electrode on the insulation substrate, an insulating film formed on the ground electrode, and a wire electrode. The root of the wire electrode is soldered to the high-voltage electrode. The tip of the wire electrode is arranged so as to protrude in a recessed part. The ground electrode has a pair of legs disposed on the insulation substrate at the sides of the recessed part. The legs are parallel to the wire electrode on opposite sides of the wire electrode. The insulating film is provided on the surface of the ground electrode to cover the ground electrode except the high-voltage electrode contacting a first terminal, a contact portion contacting a second terminal and parts of the legs of tips of the ground electrode that face the tip of the wire electrode.

A pressing wall is provided in a part of the entire area of the first carrying chamber in which a first screw member is housed. The area is opposed to a bottom wall of the first carrying chamber on the lower side in the gravity direction of the first screw member and opposed to the side walls of the first carrying chamber on both lateral sides orthogonal to a rotation axis direction of the first screw member. In the area, a toner concentration of a K developer being carried is detected by a K toner concentration sensor. The pressing wall comes into contact with, from above in the gravity direction, the K developer, which moves from a lower side to an upper side in the gravity direction according to the rotation of the first screw member, and presses the K developer downward in the gravity direction.

A speed change detection apparatus includes an image carrier for carrying a latent image, and a latent image pattern forming device for forming a latent pattern image on the image carrier. The pattern image includes periodically formed line or dot images. An alternating current conversion type surface potential sensor is provided to detect a potential of the surface of the photoconductive member. The alternating current conversion type surface potential sensor further detects a change in speed of the image carrier by detecting a moiré appearing on the latent image pattern.
