Title:
PHOTORECEPTOR UNIT, DEVELOPING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP3825939
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent toner in a developing case from being leaked because of falling and the like, and to make eliminable such trouble that a tape is peeled at a using time.
SOLUTION: A blade holder 42, a blade 17 and a reinforcing plate 43 are fitted to the fitting surface 44 of the developing case 13 so as to be laminated. Besides, seal members 57 and 59 enhancing the airtightness of an interval between the outside wall 41 of the case 13 are arranged along at least the upper edge and the lower edge of the holder 42. Thus, even when a developing roller 15 and the blade 17 are vibrated because abnormal impact acts on the case 13, the toner in the case 13 is prevented from being leaked outside through the rear side of the holder 42. Besides, such trouble that the tape is peeled at the using time can be eliminated.
