Abstract

An image forming apparatus includes an apparatus main body including an electric substrate and first and second main body electrical contacts electrically connected to the electric substrate, and a cartridge detachably attached to the apparatus main body, wherein the cartridge includes first and second process members, and first and second cartridge electrical contacts electrically connected to the first and second process members, respectively. The apparatus main body includes a common holding member holding a first end portion of the first main body electrical contact and a second end portion of the second main body electrical contact, wherein the holding member is configured to move between a contact position at which the first and second end portions contact with the first and second cartridge electrical contacts, respectively, and a separation position at which the first and second end portions are separated from the first and second cartridge electrical contacts, respectively.

Dependent claims

An image forming apparatus, comprising:

an apparatus main body including an electric substrate, and a first main body electrical contact including a first coil spring portion and a second main body electrical contact including a second coil spring portion which are electrically connected to the electric substrate;
and
a cartridge configured to be attachable to and detachable from the apparatus main body, the cartridge including:
a first process member;
a second process member;
a first cartridge electrical contact electrically connected to the first process member;
and
a second cartridge electrical contact electrically connected to the second process member,
wherein the apparatus main body includes a holding member holding both a first end portion of the first main body electrical contact on a cartridge side and a second end portion of the second main body electrical contact on a cartridge side so as not to cause the first end portion and the second end portion to be electrically connected to each other, and
wherein the holding member is configured to move between a contact position and a separation position, the contact position being a position at which the first end portion contacts the first cartridge electrical contact by spring force of the first coil spring portion and the second end portion contacts the second cartridge electrical contact by spring force of the second coil spring portion, the separation position being a position at which the first end portion is separated from the first cartridge electrical contact so as not to comes into contact with the first cartridge electrical contact and the second end portion is separated from the second cartridge electrical contact so as not to comes into contact with the second cartridge electrical contact.
