Abstract

PURPOSE:To obtain with a good reproducibility an image having a good quality and no fog by flying a toner particle, applying simultaneously a DC voltage and an AC voltage between one electrode and the other electrode. CONSTITUTION:In a developing process, a DC bias voltage V1 is applied between a base body electrode 5 and a counter electrode 7, and simultaneously, an AC bias voltage V2 is also applied. In this case, the DC voltage V1 is set to -10kV, and as for an amplitude width of the AC voltage V2, it is desirable in respect of the developing property that the total bias voltage is not inverted in case when it is added to the DC voltage V1, but there is no harm in inverting it. As for a frequency of the AC voltage V2, 100Hz-10kHz will do, and it is considered that about 5kHz is practical. By applying simultaneously the DC voltage V1 and the AC voltage V2 at the time of development, a toner particle charged with an electrostatic charge quantity distribution on the base body electrode 5 is vibrated by said AC voltage,and even if it is in a coagulated or cluster state, its coagulation is unfastened, and the cluster is collapsed.

2. Prior Art Conventionally, in electrophotographic copying methods, photoconductive toner is uniformly spread on a base electrode, imagewise exposed while applying a bias voltage between it and a counter electrode, and toner particles that have absorbed active light are selected. A technique is known in which a toner is charged and at the same time is caused to fly toward the counter electrode using the bias voltage, thereby performing development. For example, JP-A-56-33664, 56-336
No. 65 and No. 56-33666 each disclose that a direct current voltage or an alternative alternating current voltage is applied as the bias voltage.

However, as a result of studies conducted by the present inventor, it has been discovered that the above-mentioned known technology has the following problems. That is, during development, toner particles that have absorbed light from imagewise exposure actually have a charge amount distribution, and the toner particles may not move to the counter electrode side simply by applying a DC or AC bias voltage. If the positive toner image on the base electrode is then transferred to a recording material such as paper in this state, only an image with a lot of fog will be obtained due to the residual of unnecessary toner particles based on the above, and the image quality will also tend to deteriorate.

In this way, by simultaneously applying the DC voltage (2) and the AC voltage (2) during development, the toner particles charged with the charge amount distribution on the base electrode 5 are vibrated by the AC voltage, and even if they are not aggregated. Or even if they are in a cluster state, the aggregation is loosened and the clusters are collapsed. Therefore, toner particles are given a sufficient flying probability even if the amount of charge is small, and all of the charged toner particles are in a state where they are likely to fly out to the counter electrode side, so that the next transfer will faithfully reproduce the original image. It is possible to obtain high-quality, fog-free images that correspond to the above conditions.

In the above example, for example, in the step of FIG. 3 fbl, light is irradiated through the counter electrode 7, so the counter electrode 7 needs to be transparent, but the base electrode 5 is transparent as shown in FIG. The electrode may be made transparent and light may be irradiated through this electrode. In addition, in order to prevent charges of opposite polarity from being injected from the counter electrode 7 into the particles that flew to the counter electrode 7, the counter electrode 7 is insulated 1i as shown in FIG.
It is desirable to provide t13. Furthermore, if the two types of photoconductive toner particles A and B used in the above example are colored in complementary colors to each other, and if the light absorption curves of A and B are superimposed and there is absorption in the visible range, then Particle types other than those mentioned above can be used. The charging polarity of these photoconductive toners may also be opposite to that described above. Furthermore, it goes without saying that the present invention can be carried out even if only a single color toner is used.

It will be understood that by using the copying apparatus constructed in this manner, each process shown in FIG. 3 can be carried out with good reproducibility. In FIG. 7, by providing a toner thickness regulating plate 24 immediately after the toner particle sprayer 17, the toner particles can be uniformly spread on the base electrode 5 in a state close to a single layer. Furthermore, if the toner particles on the counter electrode 7 after image exposure are transferred onto another recording material (not shown) without being removed by cleaning as described above, a negative pattern image can be obtained. Further, during development, image exposure may be performed first, and then toner particles may be caused to fly.

[Scope of Claims] 1. A copying method including a step of flying toner particles from one electrode to the other electrode, and performing development with the toner particles, furthermore, transfer, etc., wherein the one electrode and the other electrode A copying method characterized in that the toner particles are caused to fly while simultaneously applying a DC voltage and an AC voltage between the toner particles. 2. When developing using photoconductive toner, the first
a first colored photoconductive toner that absorbs light at a wavelength of and becomes conductive; and a first colored photoconductive toner that absorbs light of a second wavelength different from the first wavelength and becomes conductive; 2. A method as claimed in claim 1, wherein a second colored photoconductive toner having a complementary color to the photoconductive toner is used simultaneously. 3. A step of distributing the toner on the base electrode; a step of imagewise exposing the base electrode while simultaneously applying a DC voltage and an AC voltage between the base electrode and a counter electrode facing thereto; The method according to claim 1 or 2, comprising the step of causing toner particles that have absorbed light due to imagewise exposure to fly toward the counter electrode.
