Specific embodiment
Developer supply roller of the invention can be the developer supply roller for image forming apparatus comprising have height
Molecule foamed material covers the metallic roll on its surface, and wherein the surface roughness on the surface of high molecular foam material is 60 μm or more
And less than 140 μm.
The surface roughness on the surface of material is usually defined by JIS B0601 etc., but developer supply roller is by its table
Has leachy high molecular foam material on face to be formed, therefore surface roughness cannot be measured with probe.Therefore, in this hair
In bright, surface roughness is defined as in measurement length be to be divided into 1mm between 40mm measurement and measure in the case that points are 40,
The standard deviation of the displacement for whole measurement points that the slave baseline measured is started.
Surface roughness described in detail below.To developer supply roller of the invention it is important that control rough surface
The quality of degree, but cannot be used for measuring using the surface finish measurement equipment of probe, this is because the probe is hindered by stomata.
Therefore, in the present invention, surface roughness is evaluated using laser dimension measuring apparatus by measuring the displacement apart from baseline.
In the evaluation, necessarily explore such condition: the image such as fuzzy and striped is bad to be shown and passes through
The good relationship and measured value of the measured value of evaluation method are stablized.Knot as the conscientious research made by the present inventor
Fruit, it has been found that the distance between measurement point is important to the good relationship provided between image quality and measured value
's；And it is necessary that the distance between measurement point (being hereinafter properly termed as measurement interval) is 0.5 to 3mm, and measurement point
Number is 20 or more, and more preferable 30 or more.When measurement interval is more than 3mm, will not obtain and the undesirable relationship of image；And
When measurement interval is less than 0.5mm, the fluctuation of measurement becomes larger that the reproducibility of measurement cannot be provided.
In the present invention, by being 40mm in measurement length, it is divided into 1mm between measurement and measures the case where points are 40
Under, the standard deviation of the displacement for whole measurement points that the slave baseline that measures is started evaluates surface roughness.Baseline can pass through
The least square method of whole measurement points measures to draw straight line.
More specifically, being used in the measurement such as Fig. 2 of evaluation show to carry out.The upper part of Fig. 2 is developer of the invention
The schematic diagram of supply roller, and its underpart is the schematic diagram for showing measurement method.Measurement line 13 shows laser, and will have
The interval of 1mm sequentially include 40 points from L1, L2 and L3 to L40 by with the direction shown in arrow using linear laser come
It scans and measures.Therefore, the measurement length of total is 40mm.It is used herein as the laser of Mitsutoyo Corporation production
Dimension measuring apparatus.
Then, baseline is provided by the least square method as shown in the dotted line in Fig. 2, and by baseline and measurement point it
Between difference, that is, calculate the standard deviation of the displacement for whole measurement points that the slave baseline that measures is started and be defined as rough surface
Degree.
Measurement method needs about 30 seconds durations of each developer supply roller.The quality of roller can pass through JIS
AQL (acceptable quality horizontal) inspection by sampling that Z9015 is recorded ensures.Thus it is speculated that using a grinder in a life
It produces the developer supply roller produced in the period and is defined as a batch, select the sample of the conventional detection standard I of the subordinate list A1 of JIS Z9015
Product text measures standard by the way that the table sampling of conventional detection to be measured to sample number, and according to the batch of conventional detection to survey
The qualified distribution of the fixed batch.In the case, acceptable quality level can be 0.1 or more and 1.0 hereinafter, and preferably 0.4,
Therefore the occurrence frequency of detection working hour and substandard product is within the acceptable range.In the case where unqualified batch occurs,
Detection is necessarily converted into strict inspection, and if detection is continued with the sampling frequency of conventional detection, substandard product
Occurrence frequency can become unacceptable.In the case that continuing three batches in strict inspection does not have unqualified batch, work as detection
When recovery to conventional detection, the occurrence frequency of substandard product can be within the acceptable range.Continue three in conventional detection
In the case where batch not having unqualified batch, when detection is converted into loose detection, the occurrence frequency of substandard product can be with
Within the acceptable range.In the case that in loose detection, unqualified batch occurs, detection necessarily restores to conventional detection,
And if loose detection continues, the occurrence frequency of substandard product can become unacceptable.In addition, it is thick to calculate three batches of surfaces
The process capability index of rugosity, and when process capability index is 1.33 or more, special detection level S-1 can be used, and
And the occurrence frequency of substandard product can be within the acceptable range.
The surface roughness as defined above of developer supply roller of the invention is 60 μm more than and less than 140 μm.When
When surface roughness is less than 60 μm, an adequate amount of developer will not be supplied, can cause to obscure in flying print.Another party
Face, when surface roughness is 140 μm or more, the ability for removing undeveloped developer can be insufficient, can inhibit not hand over
The number that developing apparatus can print is changed to increase.
In view of the viewpoint, preferably 70 μm of surface roughness more than and less than 120 μm.Particularly, good image can lead to
Crossing makes target reach 80 μm of surface roughness more than and less than 120 μm to retain.
