Image forming apparatus, developer cartridge and photosensitive unit
First Claim
1. An image forming apparatus comprising:
- a developer cartridge comprising;
a first casing configured to accommodate a developing agent;
a developing agent carrier supported by the first casing and configured to carry the developing agent;
a memory element configured to stored predetermined information; and
a first terminal electrically connected with the memory element;
a photosensitive unit comprising;
a second casing to which the developer cartridge is detachably attached;
a photosensitive member, with which the developing agent carrier is brought into pressure contact when the developer cartridge is attached to the second casing, supported by the second casing; and
a second terminal configured to be electrically connected with the first terminal when the developing agent carrier is brought into pressure contact with the photosensitive member; and
a main body unit comprising;
a third casing configured to receive the photosensitive unit;
a control section provided in the third casing; and
a third terminal electrically connected with the control section, and configured to be electrically connected with the second terminal when the third casing receives the photosensitive unit,wherein the first casing comprises a pressing member configured to move between a pressure contact position in which the developing agent carrier is in pressure contact with the photosensitive member and a release position in which the developing agent carrier is released from pressure contact with the photosensitive member,wherein the first terminal is provided in the pressing member.

Abstract
An image forming apparatus is described. The image forming apparatus may include a developer cartridge and a photosensitive unit. The developer cartridge may include a first casing accommodating a developing agent, a developing agent carrier supported by the first casing and carrying the developing agent, a memory element storing predetermined information, and a first terminal electrically connected with the memory element. The photosensitive unit may include a second casing to which the developer cartridge is detachably attached, a photosensitive member, with which the developing agent carrier is brought into pressure contact when the developer cartridge is attached to the second casing, supported by the second casing, and a second terminal electrically connected with the first terminal when the developing agent carrier is brought into pressure contact with the photosensitive member.
