DRIVING TRANSMITTING DEVICE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a high-quality image by stably driving a transfer belt by enhancing the rigidity of a gear for transmitting driving from a driving motor to the transfer belt and a photoreceptor drum so as to prevent the deformation of the gear without increasing cost highly.

SOLUTION: A transfer belt gear mechanism 66 for transmitting the driving of the driving motor 61 to the transfer belt 21 and a belt gear mechanism 72 having a drive gear 73 for transmitting the driving of the driving motor 61 to the photoreceptor drum 10 are integrally formed. A collar 80 having a first ring 80b and a second ring 80c is integrally formed. The collar 80 is lightly press-fit between the bearing part 66b and the wall part 66c of the transfer belt gear mechanism 66.
