Abstract
A static eliminating device includes a light guide body formed in a bar shape and attached to a drum frame, and a light source. The light source is arranged at one end side in a longitudinal direction of the light guide body. The light guide body includes a plurality of reflection parts and an attachment part. The plurality of reflection parts is arranged in parallel in the longitudinal direction within a range at the other end side from a start position spaced a predetermined distance from one end in the longitudinal direction. The attachment part is arranged between one end in the longitudinal direction and the start position to act as a start point of thermal deformation in the longitudinal direction. The attachment part is composed of two protrusions to interpose an edge of a positioning hole provided in the drum frame at one end side in the longitudinal direction.
