Description
Technical field
The present invention relates to cartridge processing (process cartridge), use the image processing system and the image forming method of this cartridge processing.
Background technology
In the cartridge processing of image processing system, in order to prevent to wait the deterioration of the picture mounting body that causes, prevent fixed (film forming) on picture mounting body such as toner or additive particulate because of the AC charging, improve transfer printing etc., application of lubricating on picture mounting body.Wherein, generally use brush roll to scrape and get the method that solid shape lubricant is coated with.
In the past, this lubricant applying brush roll looked like the mounting body relatively, in both contact positions, promptly turned round with roughly the same linear velocity with picture mounting body equidirectional towards the servo-actuated direction.If make it towards contrary servo-actuated direction revolution, the revolution load increases, and the drive division burden is big, and structure needs to strengthen, and needs to select high output motor, and perhaps load variations is easily big, and ribbon grain image etc. takes place, and picture quality is brought bad influence.
In addition, even the lubricant applying brush roll towards servo-actuated direction revolution occasion, if the brush roll linear velocity is more a lot of slowly than picture mounting body linear velocity, then easily sandwiches the residual toner of transfer printing, or lubricant applying is irregular, on the contrary, if the brush roll linear velocity is fast relatively a lot, then with identical towards contrary servo-actuated direction revolution occasion, the revolution load increases, perhaps because of load variations generation ribbon grain image problems such as (image deflects that cause because of vibration), therefore, with roughly the same linear velocity revolution.
But, in the prior art,, irregular because of spacing generation lubricant applying on picture mounting body of brush roll fibrous bundle sometimes if the lubricant applying brush roll turns round with roughly the same linear velocity with picture mounting body.Bristle configurations as shown in Figure 1, symbol 217 expression brush rolls, P represents the fibrous bundle spacing.In fact contact occasion with picture mounting body, as shown in Figure 2, symbol 201 expressions at picture mounting body linking part, are joined irregular in the front end generation of fibrous bundle as the mounting body.Be schematically represented as tabular respectively as mounting body and brush roll among the figure, actual is cylindric as mounting body and brush roll.
Under this brush joined state, as shown in Figure 3, the lubricant applying amount also became irregular by the spacing shape of fibrous bundle, when the lubricant quantity delivered after a little while, on as the mounting body, produce the zone that does not almost have application of lubricating.
In the few zone of lubricant applying amount, a little less than picture mounting body protection effect, easily cause surface deterioration because of applying AC etc., abrasion is cleaned bad.Have again, fixed (film forming) on picture mounting body such as toner or additive particulate easily takes place, or it is bad etc. that local transfer printing easily takes place, and picture quality is brought bad influence.
For fear of these problems, adopt the means of eliminating the few zone of lubricant applying amount, for example, increase lubricant and brush roll relay mutually, increase brush roll and scrape the amount of getting lubricant, as shown in Figure 4, increase the coating weight of lubricant at picture mounting body.On the contrary, in the many parts of lubricant applying amount, the lubricant remainder pushes through cleaning balde, is attached on the charging unit, causes that charging is bad, and image background takes place dirty dirty, and picture quality is brought bad influence.
Therefore, the application of lubricating occasion is to coating weight restriction bound, for coating weight being suppressed within this limited amplitude, need strict dimensional tolerence and the lubricant material deviation that limits each constituent part, maybe need to append the high price and the complicated mechanisms such as cleaning agency of charging roller or picture mounting body.
About in the image processing system to picture mounting body application of lubricating, multiple scheme was proposed, for example, open in the 2001-166661 communique (following brief note is " patent documentation 1 ") the spy, a kind of scheme of lubricant infiltration in brush roll itself that make disclosed.Open in the 2004-334092 communique (following brief note for " patent documentation 2 ") the spy, disclose a kind of except the coating brush, the formation of setting up clearer.
