Abstract

It has been established that the probability of a particular developer adhering to background areas of a photoconductive imaging surface is a function of the adhesion between the toner and the imaging surface, This adhesion is controlled by a variety of factors including the condition of the imaging surface, the friction between toner and imaging surface, toner carrier morphology, etc.

It has been established that the probability of a particular
developer adhering to background areas of a photoconductive
imaging surface is a function of the adhesion between the
toner and the imaging surface, This adhesion is controlled
by a variety of factors including the condition of the
imaging surface, the friction between toner and imaging
surface, toner carrier morphology, etc.

The above considerations suggest a simple method of checking
developer materials for background development character-
istics, If an uncharged imaging surface or a small sample
thereof is rubbed or brought into moving contact with the
developer mass, the amount of toner transferred onto the
imaging surface is indicative of the background develop-
ment characteristic of the developer. By controlling the
force with which the sample is rubbed against the developer,
its speed of movement and other test conditions, a semi-
quantitative indication may be had, The sample imaging
surface may be replaced by a paper or a glass slide to pro-
vide an inexpensive method for judging developer character-
istics in the field,
