Image forming apparatus

An image forming apparatus comprising:

• a unit used for an image forming process on a recording medium;
• a high-voltage board configured to supply a high-voltage current to the unit;
• and
• a connecting mechanism configured to electrically connect the high-voltage board and the unit,
• wherein the connecting mechanism includes:
• a first connecting member including a first spring terminal;
• a first holding member configured to hold the first connecting member;
• a coupling member with which the first holding member is coupled;
• and
• a second connecting member including a second spring terminal configured to be contactable with the first spring terminal,
• the first spring terminal includes:
• a first large diameter part composed of a compressible coil spring;
• and
• a first small diameter part composed of a tightly wound coil spring, having a smaller outer diameter than the first large diameter part and configured to be contactable with the second spring terminal,
• the first holding member has a first contact part configured to come 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, and
• the coupling member has a second contact part configured to come 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.
