Abstract

An image forming apparatus includes a unit, a high-voltage board and a connecting mechanism. The connecting mechanism includes a first connecting member, a first holding member, a coupling member and a second connecting member. The first connecting member includes a first spring terminal. The first spring terminal includes a first large diameter part and a first small diameter part. The first holding member has a first contact part coming into contact with an end part of the first small diameter part at a side of the first large diameter part in a state where the first holding member is coupled with the coupling member. The coupling member has a second contact part coming into contact with an end part of the first large diameter part at a side of the first small diameter part in the state where the first holding member is coupled with the coupling member.

Description

technical field [0001] The present invention relates to an electrophotographic image forming apparatus. Background technique [0002] Conventionally, an electrophotographic image forming apparatus includes various functional units such as a photosensitive drum unit, a developing unit, and a transfer unit, and performs an image forming process on a recording medium using these functional units. [0003] For example, there is known an image forming apparatus having: a functional unit used when image forming processing is performed on a recording medium; a high-voltage circuit board (high-voltage board) for supplying a high-voltage current to the functional unit; Board and the connection mechanism of this functional unit. [0004] In some cases, a pair of spring terminals are used to form a high-voltage contact inside the above-mentioned connection mechanism. In this case, when setting the pressure of the high voltage contact, it is necessary to consider the spring pressure o...
