Abstract

PURPOSE: To obtain an excellent image, by attaching the linkage supporting means of developer supporting means and developer layer thickness defining means fixedly or slidably to the mounting part provided on a developer supporting body, and specifying these dimensions and coefficients of thermal expansion within the specified range.
CONSTITUTION: Opposite to a latent image holding member 1 are provided, either fixedly or slidably, a developer supporting means 2, a developer layer thickness defining means 6, a means 4 to link the developer supporting means 2 and the developer layer thickness defining means 6, and mounting parts 11, 2a having the linkage supporting means 4 provided on the developer supporting means 2, thus constituting the device. The distance between linking parts of the linkage supporting means 4 at 15°C is supposed to be L, the distance from the linking part 7 of developer defining means 6 and linkage supporting means 4 to the end part to be l, the distance between the developer supporting means 2 and the end of the developer defining means 6 to be d, the coefficient of thermal expansion in distance L to be a, and the coefficient of thermal expansion in distance l to be b, and these factors are designed to satisfy the relations of a<b and formulae (1) and (2). Thus, within the operating temperature range of -5°CW35°C, an excellent image may be obtained.
