ку смешивают с носителем. После 15000 циклов, по сравнению с первым примером, качество копий остаетс хорошим, а на фоторецепторе не наблюдаетс вредного наслоени виража.ku mixed with the carrier. After 15,000 cycles, compared to the first example, the copy quality remains good, and there is no harmful layering of the bend on the photoreceptor.
Пример 3. Про витель модифицирован таким же образом, что и в примере 2, добавлением 2,0% фталеврй кислоты, средн величина частиц которой находитс в пределах от 0,5-10 мк. После 5000 циклов качество копии, по сравнению с первым примером, лучше с меньшим наслоением виража на фоторецепторе.Example 3. The producer was modified in the same manner as in Example 2 by the addition of 2.0% phthalic acid, the average particle size of which is in the range of 0.5-10 microns. After 5000 cycles, the quality of the copy, as compared with the first example, is better with a smaller stratification of the turn on the photoreceptor.
Пример 4. Про витель модифициролан тем же способом, что во втором примере , добавлением 3,0% изофталевой кислоты , средний размер частиц которой колеблетс от 0,5 до 10 мк. После 5000 циклов качество копий значительно лучше, чем в первом примере, при гораздо меньшем наслоении виража.Example 4. The producer is modified in the same manner as in the second example, by adding 3.0% isophthalic acid, the average particle size of which ranges from 0.5 to 10 microns. After 5000 cycles, the copy quality is much better than in the first example, with a much smaller layering of the turn.
Пример 5. Про витель модифицирован , как и в-примере 2, добавлением 1,0% соли натри терефталевой кислоты, и полученной при взаимодействии 2 молей NaOH с 1 молем кислоты. Средние размеры частиц соли колеблютс от 0,5-10 мк. После 7000 циклов качество копий значительно лучше, чем в первом примере.Example 5. The pro ductor is modified, as in Example 2, by adding 1.0% sodium salt of terephthalic acid, and obtained by reacting 2 moles of NaOH with 1 mole of acid. The average size of salt particles ranges from 0.5-10 microns. After 7000 cycles, the copy quality is significantly better than in the first example.
Пример 6. Про витель модифицирован как и в примере 2, добавлением 0,25% соли кали изофталевой кислоты. Средний размер частиц соли колеблетс в пределах от 0,5 до 10 мк. После 7000 циклов качество копий значительно лучше.Example 6. The manufacturer was modified as in example 2 by adding 0.25% potassium salt of isophthalic acid. The average salt particle size ranges from 0.5 to 10 microns. After 7000 cycles, the copy quality is much better.
Пример 7. Про витель модифицирован тем же способом, что в примере 2, добавлением 1,0% соли цинка терефталевой кислоты. Средний размер частиц соли - 0,5-10 мк. После 7000 циклов качество копий значительно лучше, чем в иримере 1.Example 7. The producer was modified in the same way as in Example 2 by adding 1.0% zinc salt of terephthalic acid. The average size of salt particles is 0.5-10 microns. After 7000 cycles, the copy quality is significantly better than in the irimer 1.
Пример 8. Про витель модифицирован тем же способом, что и в примере 2, добавлением соли аммони терефталевой кислоты. Средний размер частиц соли 0,5- 10 мк. После 7000 циклов качество копий значительно лучше, чем в примере 1, при меньшем наслоении виража.Example 8. The producer was modified in the same manner as in Example 2 by the addition of an ammonium terephthalic acid salt. The average size of salt particles is 0.5-10 microns. After 7000 cycles, the quality of the copies is significantly better than in Example 1, with less turn layering.
Пример 9. Технологический ироыесс, описанный в примере I, но копировальноеExample 9. Technological and technological solutions described in example I, but copying
устройство оборздовано винилкарбазоловым фотопровод шим элементом. Уже после 500 копий, как и в примере 1, наблюдаетс наслоение виража при заметном ухудшении качества копий.The device is surrounded by a vinylcarbazole photoconductor shim element. Already after 500 copies, as in Example 1, layering of the turn is observed with a noticeable deterioration in the quality of the copies.
Пример 10. Технологический процесс, оиисанный в примере 9, иовтор етс за исключением того, что нагруженный виражем фотопровод ший элемент, даюший изображение того же состава, и про витель модифицирован добавлением терефталевой кислоты , средний размер частиц которой колеблетс от 0,5 до Q.MK. Модификаци образована простым однородным механическим перемешиванием терефталевой кислоты , вз той в количестве 0,29% от веса виража с виражом. После этого вираж и добавку смешивают с носителем. После После 15000 циклов качество копий остаетс относительно однородным по сравнению с первым примером, а наслоение виража незначительно.Example 10. The technological process described in example 9 is repeated except that the photoconductor loaded with the turn is an image of the same composition and the developer is modified by adding terephthalic acid, the average particle size of which varies from 0.5 to Q. Mk. The modification is formed by simple homogeneous mechanical agitation of terephthalic acid, taken in an amount of 0.29% by weight of the turn with a turn. After that, the turn and the additive is mixed with the carrier. After 15,000 cycles, the quality of the copies remains relatively uniform compared to the first example, and the layering of the bends is negligible.
Опнсываемый электрографический модифицированный про витель обеспечивает длительное сохранение хорошего качества копий, а также минимальное наслоение виража на фотопровод шую поверхность элемента , даюшего зображение.The modified electrophotographic modified developer ensures long-term preservation of good quality of copies, as well as minimal layering of the bend on the photoconductive surface of the element giving the image.
