Title: Imaging device
Inventor: TAIRA HIROSHI
IPC: B41K1/50
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of stepwise crease in an ink ribbon when the rear end of a document sheet is drawn out after printing is performed on the surface of the document sheet by means of a thermal head and a platen roller through an ink ribbon. SOLUTION: In response to a print command from a controller, an auxiliary print part 8g elongated in the breadthwise direction of a document sheet 8 is formed in the vicinity of the rear end thereof. Since ink in an ink ribbon 15 is fused at the auxiliary print part 8g and then solidified, the ink ribbon 15 is temporarily bonded in the vicinity of the rear end of the document sheet 8. Consequently, an appropriate tension is generated in the ink ribbon 15 between the auxiliary print part 8g and the clamping part of a rotary driving platen roller 13 and a thermal head 12 even if the rear end of the document sheet 8 passes through the clamping part thus preventing occurrence of stepwise crease.

IPC: G03G15/20
Filed: 1985-12-10
Abstract: PURPOSE:To provide wear resistance to both a heat fixing roller and a pressure roller and to prolong the life by interposing a heat-resistant rubber layer which has nearly the same elasticity with the heat-resistant rubber layer of the pressure roller between the metallic layer and coating film of the heat fixing roller. CONSTITUTION:The heat fixing roller 2 and the pressure roller 3 which is made of the heat-resistant rubber layer pressed against the heat fixing roller 2 are provided and the heat-resistant rubber layer 11 having nearly the same elasticity with the heat-resistant rubber layer 7 of the pressure roller 3 is interposed between the metallic layer 4 and coating film of the heat fixing roller. The heat fixing roller 2 and pressure roller 3 are pressed against each other to deform elastically and similarly because the heat-resistant rubber layer 11 of the heat fixing roller 2 and the heat-resistant rubber layer 7 of the pressure roller 3 are made of the same material, thereby forming a plane nip 8. Further, the width D of this nip 8 is increased because the heat-resistant rubber layers 7 and 11 of both rollers 2 and 3 deform elastically and similarly to form the nip. Thus, the heat fixing roller and pressure roller deform almost similarly, so abrasion is small and the life of the device is prolonged.

IPC: G03G9/08
Filed: 1990-10-17
Abstract: PURPOSE:To improve cleanability and to prevent filming as well as to stabilize image densities by sticking a specific ratio of specific composite external additives to toner surfaces. CONSTITUTION:The composite external additives consisting of magnetic powder, silica and titanium oxide are stuck to the toner surfaces.
