Abstract:
A developing device includes an accommodating casing, a rotatable developer carrying member, a regulating portion, a magnetic flux generating portion including a first magnetic pole and a second magnetic pole which have the same polarity, and a cover portion provided downstream of the developing region and upstream of a maximum magnetic flux density position of the second magnetic pole with respect to a rotational direction of the developer carrying member. The cover portion is disposed between the casing and the developer carrying member. A downstream end of the cover portion with respect to the rotational direction is in a side upstream, with respect to the rotational direction, of a minimum magnetic flux density position between the first magnetic pole and the second magnetic pole with respect to the rotational direction.

Claim (Index 22):
A developing device comprising:\n an accommodating casing configured to accommodate a developer; a rotatable developer carrying member provided in said accommodating casing and configured to develop, in a developing region, an electrostatic latent image formed on an image bearing member; a regulating portion provided below said developer carrying member with respect to a vertical direction and configured to regulate an amount of the developer on said developer carrying member; a magnetic flux generating portion provided inside said developer carrying member and including a first magnetic pole provided downstream of the developing region with respect to a rotational direction of said developer carrying member and a second magnetic pole which is provided adjacently downstream of said first magnetic pole with respect to the rotational direction and which has a polarity identical to a polarity of said first magnetic pole; and a cover portion provided downstream of the developing region and upstream of a maximum magnetic flux density position of said second magnetic pole with respect to the rotational direction, said cover portion being disposed between said casing and said developer carrying member over a rotational axis direction of said developer carrying member with a gap between itself and said casing and with a gap between itself and said developer carrying member, wherein an upstream end of said cover portion with respect to the rotational direction is in a side upstream of a maximum magnetic flux density position of said first magnetic pole with respect to the rotational direction, and wherein said cover portion is disposed so that an opposing region between an inner surface of said casing and said developer carrying member is in a side downstream of the developing region and upstream of the upstream end of said cover portion with respect to the rotational direction.
